Tuned Porsche 911 991.2 Carrera 4S vs Stock Carrera 4S 

Nick, I didn't know the alcantara wing was available. I need to get that for my Corolla. Merry Xmas! Thanks for your channel.

What I want to see is a tuned base model against a stock S

Id like to see turbo temp, water temp and oil temp numbers posted. Then you will have a good indication of the effects of the tune. As someone else noted, theporsche turbo has many more cooling bits to calm the fire.

I had a GIAC tune on my mkiv Gti and it was a night and day difference. 50hp and 50tq for only 600 dollars. GIAC makes some of the most reliable tunes out there.

Dit the tune for my 17 991.2. Big difference for sure.

Cheap HP in Porsche money. The sound is the only thing missing in the turbo cars, but can't have everything. Love that color...

tuned 991.2 vs turbo please

The tunes I know about on 997 turbos increases the maintenance schedule, especially plugs - which are difficult to replace because of where they're located. Not a problem necessarily, just something you should be aware of. But honestly, there's no way Porsche will cover any major service issues if your car has a tune. If your heated seats stop working sure, the tune won't matter in their eyes, but any mechanical problems and they'll blame the tune. I'd give it a couple of years, wait and see what tuners learn after these cars run their tunes for 30000+ miles. The 997 tuners know exactly what can happen and explain it all in detail. I'd worry I was guinea pig in the tuners experiment with the 991.2 because it's still so new.

That howling flat six is intoxicating....

Nick, William looks a little depressed....he probably just needs a bit more sunshine in his day. lol...... Hey in all seriousness I hope you have a wonderful holiday and a very Merry Christmas. Enjoy all your family coming to visit in your beautiful home. Thanks for all the fun and good humor (and learning a thing or two about cars) that you gave us in 2017. Cheers to a glorious 2018.

A 911T tuned could be a great bargain.

I wouldn't touch a tune on a car that is still under any kind of warranty for obvious reasons. Sure, some might say it "shouldn't be an issue" but tell that to the guy that blows his engine and now has a $40,000 bill to replace it and the dealer/regional service rep finds either the tune or data collected that indicates higher boost ranges only possible by the tune. I have seen this happen in the past with less expensive cars, and you better believe it would happen with a Porsche. Outside a warranty? I am all for the Tune!

Hi Nick! Happy holidays! We got our 06 Boxster S tuned years ago and it was amazing the difference even for a NA car. Optimize for an exhaust and even better. Porsche has so many restrictions from the factory you really do get a bit of lowest common denominator action. I bet that was fun! F

So how is the tuned C4S holding up (maintenance and issues wise) compared to the stock C4S after five years? Thinking about doing work to my 991.2 C4S after the warranty expires.

Nick you gotta tune yours

Great Video Nick! I’d love to see a GIAC Tuned 991.2 base 911 vs. a stock 991.2 911S.

6:06 The Turbo now has 540hp not 520hp , i only watch Nick videos to catch a mistake or 2 ;)

Nick your use of go pros and dslr camera really adds to the production value. I know editing takes longer but well worth it in the end.

There is no way Porsche UK would allow a customer to tune their carrera without it affecting warranties.. shame.. Great video though!! Hope you have good Christmas and all the best for 2018! Cowan

Tuned C2S - Widowmaker is Back

Love that graphite blue metallic!

...but Nick, your a major gearhead, so you NEED that tune and now that you just helped to sell thousands of them yours should be FREE🤔 Merry Christmas 🎄

Great video Nick. These cars definitely need to be unlocked. I suffer from horsepower inferiority complex (H.I.C.) after paying over $100g for a car that wont keep up with a new Mustang GT. I have a 991.2 C2 manual that I’m planning to upgrade with Cobb’s off the shelf map and maybe upgrade the intercooler once my warranty is up. GIAC’s bench flashing sounds like a pain as you are carless for a couple of days waiting for them to ship back your ECU. Cobb has a plug and play platform through an OBD II port and sounds user friendly. You should definitely tune your car as there’s an uninstall feature. Also can you do a comparison video between the Carrera and Carrera S and go over the value proposition for road use and occasional track. With these new ECU tunes coming out, it makes it harder to choose an S unless you desperately need PTV, 6piston brakes, rear wheel steering. I agree with your stance on the GTS. Thx

Always such a breath of fresh air to watch Nick's videos - Happy Xmas Nick!

Was stock 992 carrera 4s here, and dragy timed me 2.8-2.9 run after run on a tire only. 991 and 991.2 pdk’s are def tuned different. Stage 2 now I’m running turbo S numbers. PB 10.1 quarter mile, on pump 94. Mind you, it’s premium Canadian Petro 94 / E10, super clean gas. These cars are insane either way. Ethanol is the deciding factor in the end for more power. None here except by the barrel! 🤷🏻‍♂️

Nick, ecu tune crossed my mind as well, where I ended up was it’s less about a local service shop’s view point, rather once they plug in your vehicle, Porsche will receive the data points on your car. While nothing will happen at that point, there would be the issue if something does happen to your engine etc, they can point to the software regardless. Sure your can spend the energy fighting this back and forth if you have the time. For me, the real deal breaker was, these are still relatively new engines to the market and would like to see more feedback in a years time. Thoughts?

My Audi dealer actually sells the APR tune in their service dept (which I did get). They are cool with it, but technically it does void your warranty and it says that on the invoice. However, they imply that you could switch the programming back to stock for any potential warranty claim as the tune can be reverted between stock and tuned programs by a simple switch.

I guess the only reason to buy a Turbo is to say you have a “real” Turbo..... And is that Graphite Blue Metallic? It’s freaking gorgeous!! Love it! Almost as good as Speed Yellow!!

A tuned 4S vs the turbo please! Great vid!

Amazing - and makes it even better to know you can buy the lower model than the Turbo and have the OPTION to go up in power to match it.

Hey Nick, do a video on the next generation 911. Yea baby!

Have an '04 Mini Cooper S JCW bought new. Love it, have no intention (or ability) to get a Porsche. Last had a couple in LA in another life. But I really enjoy your posts. So joyful, which is the whole point of driving, whatever you drive. Mahalo!

Happy Christmas everyone! Nick, look for that Turbo and compare it to Mike’s C4S. Then you can decide if you want to chiptune your car. Not that there are reasons not to do it, since you have a manual gear and even as a stock car it’s difficult to compare it to others since nearly all Americans buy the PDK versions. If you decide to do it, let your dealership install the new chip. I did that with my Audi, and that way at least you’ll keep the guarantees on the car valid. Thx for the vid, like always! Cheers, Irwin

I like that this gets you close to turbo power but lets you keep the stick that I wish where still an option on the turbo!

That's the great thing about turbo motors, such a large increase in performance is great bang for buck compared to tuning an NA motor. These 991s will be monsters once they get a little older and aftermarket support increases.

Tunes are great. We did one on our Porsche Boxster. So worth it. I seriously doubt the tune will hurt your car. Heidi

Oh that glorious engine note... That alone was worth the like. :-) Merry Christmas Nick!

Awesome video Nick...and an impressive improvement...wow! Yet I'm not 100 percent convinced Porsche NA will cover an engine issue that has had its pcm tuned ..I'd recommend waiting until after warranty is no longer a concern to owners..80 hp and 100lb ft of tq for two grand mit be too tempting to not say good bye to the warranty! Merry Christmas Santa came a day early

Inspiration Nick Iam a fellow Kiwi to working my way to the 911 Iam at the cayman stage at the moment keep up the awesome videos

I went for the full meal deal with my Turbo S stage IV tune, turbos, larger exhangers and exhaust...really turned into a beast...you should go for it Nick..life is short...tune it !!

I think Porsche calibrated the boost pressure such that the torque stays constant and subsequently the power builds linearly. Ye know, preserve the feel of the old N/A engines. The Turbo has that low down shove

That color, sunroof delete, nice wheels...winner!!!

Can I just add that I think 1985 was a great year for cars. Perhaps because I got my DL that year. My favorites from that year are mustang gt and svo. Iroc and trans am. Porsche 928 and 911 and 944. Even though 944 had a vw rabbit interior.

The Color on the tuned 4S looks so good - and it seems to be a Bit lower compared to the stock one; very nice !

Nick, Mike’s car also has a Speedtech Exhaust system. Might have been worth mentioning that exhaust in combination with a tune is a great combo mod. Nice video!

Nick, I think you should definitely look into getting the tune. I don't know how it works with your engine, but in my N54 BMW 135i I can flash the stock map in less than 2 minutes as well as reflash the tune in the same amount of time with my android device. If it is that simple with your car you should get the tune and just flash back to stock for comparison videos

I just saw this now. Excellent, informative video, Nick. I assume that if you want to mimick a turbo to some degree, then it's best to do this tuning on a 4S. My question is whether you think that if one does it with a S (RWD), then might you see more fishtailing or oversteer when driving on a track? Whatever the case, this seems like a great mod that's easy to do.

A Nick Murray video for Christmas! Thanks! Merry Christmas .

How much money did the Tune run you? What Specifically is the Tune Called, Who did it, and what exactly do they do? Do they hook up to your PCM and press update and it loads the new tune? Looking at a TT Porche and I am very familiar with Tunes via my Corvette. I tuned it on a Dyno many times via HP Tuners (or LS1 Edit), but curious about the Porche's and understanding their tuning proceedure, cost, etc etc

Did you also know, all Mercedes-Benz models these days are turbocharged, except for the GLE350. But in turn, every car that wears an Audi badge has a turbocharger in it or two (except for the R8). The company still put superchargers in most of their models and they haven't gotten a chance to kill all them of and replace them with new turbos.

*Nice to see that the tuned 911, has a proper transmission.*

Wow, to pull away like that is a significant change. Thx!

I just got a 2018 4s and consider a APR stage one. I still have 4 years of factory warranty/unlimited miles. Could you give any advise on have the tune and not void the factory warranty? Any tune friendly Porsche dealership you recommend? Thanks! Love your video!

Aahh - that sound after 6:43 is the best of the entire video :-)

It will invalidate your warranty if you do this. He says the guys at his dealer don’t have a problem but if your engine gives out then I’m sure the tune will be used to inform you they’re not picking up the tab for the replacement.

Nah there are risks that come with tuning. Dealerships won’t help you in case something goes wrong and I’m sure fuel economy is affected.

Hmmmm. I have a ‘17 Audi S7 with a twin turbo engine. A ton of people on the forums tune it but I’ve not given it much thought before. I know they’re different cars but the stage 1 in your video truly looked like a different engine altogether. After watching this I can’t say I’m not tempted. The warranty though....

Very tempting indeed! Thanks and Merry Christmas Nick!

The difference is massive and a great opportunity to tune once bored of the current power. Did the owner say how much of an increase in torque/power the uprated chip achieved?

Surely the pavement was so cold that tires would spin.

That is an insane difference. Thank you for the video. Merry Christmas.

Hey Nick, I was thinking would it be possible to do the opposite and limit the torque curve instead, making it feel more like a naturally aspirated engine? I believe Ferrari applies the same trick on lower gears on 488/California T. Thank you for the video and merry Christmas!

Dealerships don't care if you tune or not, but if shit hits the fan, they will not cover you under warranty

Nick, does a 911 Turbo have the same tuning upside options available to get even more HP and torque?

Merry Christmas all n happy holidays. Thanks Nick, you just saved me a bucket load of money from not buying the 911 Turbo instead buying the 911 C4S. I'm not interested in track racing, but tuning this kind of vehicle makes a big difference to an everyday drive. Maybe I will look at an aftermarket sports exhaust kit as well, this will absolutely kill it.

Hi Nick, could you do a carrera 4 vs carrera 4s comparison sometime soon? Thanks!

Hey Nick, it would be great for you to post the wheel and suspension specs on that tuned C4S ! It sits and looks perfect, and those wheels look great.

I'd like to see this vs a Turbo

Ladies and gentlemen, the Kiwi Charlie Brown.

Wow!! I had no idea that a simple tune could make that much of a difference

Who tuned the car, where is it available, does it void factory warranty ?

probably damages the clutch sooner though

Nick, love the content as always. Top class.

Can we please Please PLEASE see the (tuned) red 996TT against the (tuned) 991.2 C4S. 🙏 I want to upgrade, but dont know how much i will/wont be giving up. Seemingly similar engine. Thanks!

That's an amazing amount of performance gain, especially especially when you no longer have to touch a wrench and/or spend hours installing a bunch of ill-fitting hardware on your engine. Does installing the tune effect your factory warranty?

When you say your service staff/dealer is okay with a Stage 1 ECU tune, does that mean they're still honor the warranty that comes with the car? Cause if so, that is incredible, I'd get that 911 tuned right away

AWSOME! Take a great car and make more. Even seems to sound better. Merry Christmas and Dilly! Dilly!

If you have the opportunity it be great to see a Boxster tune against a stock Boxster

That was really interesting and quite a difference. I wonder if the dealership could spot a retune as I guess you have to open the ECU unit. UK dealerships will invalidate a warranty on the spot if they notice - as I have been warned unfortunately.

I agree,,long as u don’t punch the much ,,the car last long..

Nick, great video. I would not do it on my new GTS because it could cause warranty problems.

It's not always about the power. Keep yours stock Nick. You know if you wanted more power, you would have bought something other than the 4S.

WHere to buy this tune? and what wheels on the modded 911, they dont appear stock?

Just checked what GIAC can do for my GTS...530hp/500tq. Unreal, that's seriously Turbo territory.

Idk how you have the control to not tune your car. I squeeze every ounce of horsepower I can out of my m3, even though 9 months ago I swore I would only get an exhaust. My last mod was an ess 625 supercharger. That brought it to 554 rwhp and I’m still wanting more. Help I think I’m sick 😦

Rematch for the carrera gts you filmed a couple videos ago.

Merry Christmas Nick! 🌲Enjoyed the video. Entertaining as always!

I wish I had friends with cool cars.

Thanks for the upload. Unfortunately most of my friends own corollas and civics so I'm kind of jealous.

Gotta see a race with the turbo! Also track down a tuned non S for a vid. Fun stuff!

I'm not sure that it would compare to the Turbo. Not the 991.2 anyway. Will have to see some drag times to find out, more than anything.

I love the color of your friend’s car.

What is the DISCO STROBE LIGHT in your garage ?

Great job Nick, I love your videos!!

There is a reason why the turbo's aren't allowed to roam free from the factory, but I'm pretty sure the tuning company doesn't know or even cares about this. They'll sell you the tune, but when things break you'll be SOL. The 991.2 is fast in all trims...wanting it go faster is silly in my mind. Porsche is very conservative with their 0-60 numbers on this one. I think under 3.5 is quite realistic for a stock car. The previous generation sounded better, but was noticeably slower, especially off the line it had some hesitation.

Do it. You know you want to, and so do we.

The tuned car has a different ride height, camber, and may have wheels spacers.

Merry Christmas Nick. What happens with warranty after this tune?

When you want to show how much faster your car is than a 996, let me know. I can come down from Newtown to Fairfield or wherever you'd like to meet. Also have a tuned Audi S6 if you ever want to compare to a family sedan 😁

love the Agate grey.
