DYNO VIDEO on these mods link is below ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-btVTigcy8Tw.html

Good video. Finally some info from a truck guy that actually drives his truck.

Thanks. I am already impressed with the stock 5.3 Vortec in my '99 Silverado, so am excited to try these tips.

I like the amount of miles on this thing, makes me happy to see trucks go the distance

Can you make a video about wearing sunglasses on a extremely cloudy day? Pro/con

That's badass bro I love that truck I appreciate the tips I'm working on my 5.3 now

Have a 5.3 that needed a new head gasket about a year ago. Mechanic talked me into going ahead and changing the heads. Put some camaro z28 heads and it screams. Definitely tell a difference.

Did you do a video showing what settings you changed on the tuner? I have a superchips tuner on my 07 Avalanche with a 5.3L and I’m currently running the 87 octane tune.

"the mod that made the biggest difference, and I know I'm gonna get the comments, but the vortec max badge makes the truck stand out"

Gotta love all the experts out there.

You should definitely mention in a video on how you feel about squated trucks, love the channel!

Hey brother, we have a 04 Silverado z71. What is the best way to tune the 5.3? We put an eBay cold intake, have flow master dual exhaust. Agree with you, to max out the engine performance with aftermarket parts, must be tuned right. Great video man. Just subscribed and gave you a huge thumps up!!!

I swap lq9 6 years ago and absolutely love the power. I installed a superchip about a year ago and you can feel the big difference. I have so much power I've done some burnouts. Take it easy

I agree with you, I did the electric fan swap and man it made a huge difference in power, mileage, plus my ac stays cold all the time

what electric clutch fans did you use. where did you get them from

I have an 05 Avalanche that has the dual clutch fans on em. And on coldish days like 40 to 60 degree weather it'll wheelspin at half throttle. On 75 to 85 degree days it will take forever to get to 60 at half throttle. So your right about the electric fans.

I fell asleep watching this video and woke up you were still talking. !!!!!!!!

X and h pipes make more power than two separate pipes because they equalize the exhaust coming out of the exhaust valves in the cylinder heads. They create an exhaust siphoning affect where two separate pipes cause the exhaust strokes fight against themselves.

What size lift are you using to run the 35s

That diablo sport tune is legit. Used it on my truck, it increased power big time, especially when you manually tune instead of using their preset tunes unless you switch to 93 octane tune and you actually start using 93 octane

Everybody told me I was crazy for saying my exhaust and air intake combination made more power on stock size wheels.. and now someone else has felt the power gains good video

I have the same electric fans in my 07 classic. Good to know man!

Bad ass truck man I love it first video I watched of yours. That is a beautiful beast.

Good info thanks bro. I'm on a mission now

Haha nice hearing Lynchburg on RU-vid, my home town

I did the E fan swap on my 2000 Sierra. I installed a 2005 Escalade radiator, and the fans from a 2009 Escalade with a 6.2. I can pull a 2500 gallon water tank out into the desert with A/C on 5 MPH to our wildlife drinkers in 110 temps. Wont get hot, stays at 210, wont move past that.

Great vid ,Question does a 2000 Yukon have the TM ?

You speak well. New sub. Keep up the good work. Nice truck

I need a video on what you did with the tune.

What abouth a cam and a install gears trasmission???

I have an 04 with 86k on it. Great truck. Check engine light is on. I get a tighten gas cap msg. Replaced the gas cap brand new. Still get the msg. Don't know if it's o2 sensor or coil pack. But I was already looking at msd as a well deserved upgrade with fresh plugs and wires.

Wow... now that I see that you and I have the same truck..... other then that I have a stock 6.0L NONE 4X4... I like your truck more... I was feeling same type of way because of the vortex max Badge thinking that you had a big boy monster engine.. lol.. THANK YOU for not hiding what you are Proud of.....

I agree with all these mods except the plugs. Better stay with the Delco iridiums. LS motors can be finicky with aftermarket plugs. Side note: a CAI with a plastic tube stays much cooler.

I feel the other mod will be a cam or long tube headers like that. I have street fire coils on my 03 5.3 and i love them.

I got TRQ performance coils in red from 1A Auto for $195 and red spark plug wires made by Summit Racing for $50. Really looks and performs well.

Thank god your doin a video on the fans!!!

The Max package includes the 14 bolt rear axle, LQ9, 4.10 gears on 4x4’s, and a 4L70 transmission. It’s far more than just a badge and an engine. It’s a new drivetrain.

I went with the acdelco iridium plugs, but I also like the NGK.

Clean truck man 👌🏼

Good video guy. Not many ppl can keep talking like you do and keep attention. This video answered none of my questions but I watched it all. Ef da h8rs

Can you do a tune video and go over what you changed from the quick tune.

You should try ac Delco rapidfire platinum plugs, they’re an upgrade from the standard platinums. And msd wires might make a difference.

Torque management deleted is most of inTune can tunes. Zeroing fuel trims at cruse rpm. Add a little fuel and timing to compensate for intake and exhaust improvements.

Hey man I have the same motor in my 02 Silverado and literally have the same mods however I have true duals like you but I have long tube stainless steel headers on my truck with the cats but w/o the mufflers and my truck sounds awesome in the cab 👍🏾👍🏾

F the haters. They are everywhere!!! Sweet truck!

keep the badge . even a stock 5.3L vortec is a strong motor as is. plus all those mods you got. good job. i got a tahoe 03 with 5.3 L with 98MI .i was considering doin some mods so thanks for the info

I'm a Bow tie owner I have a 2001 Silverado 5.3 with a Magnusson supercharge pasesetters long tube headder with a com cam harden push rods and valve springs k&n air filter system it methanol injected higher flow injector with rebuild performance transmission. also Eaton poss rear end 3 inch exhaust flow master muffler let me put it like this it's crazy fast and some outher fun things.

Really good work and great info. Since Watching this and doing some homework I put cai and H pipes on my 2015 1500, 5.3. Yes sir very noticeable. So now I can keep playing w it. Just for personal satisfaction, I don't race.

I did a cam, full exhaust, S&B cold air intake plugs and wires and a tune in my 05 Sierra crew cab z71 and it’s a complete different vehicle. Beats a ford Ecco boost in the quarter mile 🤘🏻

The best next mod u could do is long tube headers . Single most power adder u can do to these motors minus a cam

Do you know how much you spent on intake exhaust and tune together? Thank you 🙏

Wow that is a nice looking exhaust job. I love the 40s blub ,blub, blub, blub Headers No Cats.

Sweet truck bro! What’s your gas mileage after tune?

Va here to bro 🤘🏻

any link for the electric fans?

I have the diablo tuner for my 5.3 and used the preset 87 octane. What other adjustments did you do to the tuner to help your truck run better?

I had both the 6.0 and 5.3 but the 5.3 feels alil better on take off but the 6.0 is a towing beast

I like your truck,it looks nice. I won’t harp on the Max tag you’ve addressed that,no biggie. I own a 2003 Silverado SS,not crazy rare but rare enough. My point is,I see a 4x4 jacked up with running boards,stacks and an SS badge stuck on the door and I think “why”!

What type of electric fans are you running? I have an 04 Z71 Chevy Tahoe Stock 4L60 went up so I'm using one from an 02 Blazer, and rebuilding the old core to a 4L65E til I can find an 80 to build and install Then plan on running a larger intercooler with electric fans so she can handle the hills of WV better, then I plan on getting the MSD coils with NGK iridium plugs. But I do want to upgrade to the X pipe, have the CAI

Diggin that MSHA tape my dude haha I use on everything lol nice truck and awsome video

Dude I love you’re truck!! Where’d you get you’re mirrors?!

Been trying to figure out what i can do to my 5.3 vortec on my avalanche and this really helped!! Yee

"Superchargers are robbing power to make power", wow your a total genius, you must really know your stuff, I'm guessing you must be a pro tech, nice keep up the good work

Hey man.. great vids.. gotta question.. have you ever had a clunking noise coming from the back off the truck when you hit the gas from a stop?? If so what did you do to fix it.. would really appreciate it..

Msd coils in my 02 world of difference man

I should of got me a 5.3 Chevy instead or this junk 5.4 Ford

Really enjoy these vids I have an 03

Good video I learned a lot. For. My 2003 single cab gmc z71 cool truck

They should rename it hot air intake. Factory plastic tubing is far better at shielding heat. The factory unit also pulls in cooler air from outside the vehicle.

Hey man, nice truck. I just don't agree with what you stated about supercharger vs turbocharger and using power to make power. Yes the supercharger takes direct power from the engine. But the turbo creates back pressure which is robbing power too. Thus using power to make power. Maybe not as much but it still is there. And your electric fan is just moving the power draw to your alternator. Now you can say the electric fans only use power when there on and I completely give that to you. But when they are on you're just pulling power from your engine via the alternator instead. But honestly I do love your truck man!

Will the Diablo tuners work with putting a cam in the 5.3 I have a 06 YukonXl I was thinking of a stage 2 or 3 low lift cam eventually and they come with the upgraded springs from texas speed performance plus porting and polishing the heads

Nice engine and work under the hood with the paint. Is that a cleetus McFarland t-shirt awesome videos

Hey man can you get with me on the shift points you used I'm trying to help my wife's Tahoe get better power and fuel mileage im using the super chip tuner

Can I pose these all to my parents as "it'll get me better mileage"?

Will your tuner work on multiple vehicles...or is is manly for the 5.3? I got a 04 burb w/230k ...not sure if I should try to tune it or if I'm a little late on its life spam....just tired of the bog while pulling the 27ft camper...whats your opinion? 04 suburban z71 233k Everything factory

I have my lovely stock 5.3 silverado LS and plan to keep it as stock as possible. Only thing I'll change is damages from when I wreck it every so often and wear and tear replacements. It's a 2001 with 270,000 miles. Have you had trouble with your dashboard cracking?

Number one change in lS is cam swap, exhaust, cold air, then tune!

If you have some miles on that engine you'd be a helluva lot better off with a set of injectors over a set of coils

I added the diablo sport to my stock 5.3 and it came alive., probably increased 40hp easy. I just need to manually tune it to get better results.

What kind of tune did you run in it and also What kind of electric fans are you running I know u said they were 10k cfu but are they double what brand are they thanks bro

The factory coils are more then enough. The factory coils are fine in turbo 1200hp trucks.

I could roast you with my stock 6.0 gmc but you got a killer truck bro.

So doesn't your alternator have to rob power to produce the energy for the electric fan? Basically the electric fan is more efficient than the direct drive with clutch?

I heard the MSD coils were spotty and hit or miss (from reviews on amazon), don't know how true that is. I have accell super coils and Taylor cable 10.5 mm plug wires on my 06 Denali and couldn't be happier.

I like to put 6.0 badges on my 6.2 and funny story everyone laughs and thinks its a 5.3/4.8 so people are always trying to race me with their slow trucks 😂😂

I wanta put a 5.3 engine in my 84 caprice classic..

the L86 6.2L truck motor rated at 420HP can be upped to 455HP just by changing the intake manifold. That is the only difference between the LT1 and L86 motors. Chevy uses longer runners on the L86 so the higher torque comes in at lower rpm 4100, but the motor loses 35HP at higher rpm. So just change the intake and pickup 35HP. Camaros and Corvettes have LT1 motors.

Thoughts on a diablo stock tune? I’m not trying to burn the tires off or anything all I have is a cold air intake and I just Want to disable v4 and add firm shifting

Can I do the same mods to my 4.8?

Stock intakes pull in outside air. Your intake is sucking in hot engine bay air. Cold air is denser and makes more power

you noticed a change in fuel efficiency with Magnaflow? what was it, better or worse and how much?

Could those mods work for a 1999 Chevy suburban 5.7?

309k miles man i see you. i really don’t care for performance on cars/trucks if i want to go fast i just hop on my bike when i want to cruise i use the truck🤷‍♂️

Hey bowtie I got a 2005 Chevy Silverado LS 2wd.whats the best lift for it.can I do a 7-8 with fox shocks and all that good stuff

Good video. Thanks for sharing.

if u want to feel a difference get the extreme hd servo from global transmission for only 175 will definitely tell a difference or some headers would be nice especially with ur exhaust set up f*** paying 400 or whatever u said for coils u won’t even be able to feel or tell u did

I think The most popular mod for the 5.3 would definitely be bigger cam
