Shocked at the 29-30 mpg hwy at 65 mph. These trucks are so ready to work if they weren’t hampered by the EPA. Good video 👍

29MPGs x 50Gallons =1450 miles per tank. EPA needs to reconsider their non-environmental friendly crap they put on these machines. Oh another thing, love the fact that we are saving the planet by filling the DEF fluid from non-reusable plastic jugs. Government efficiency and brains at it's finest. Fine people that roll coal, let everyone else enjoy a hard working truck

This is probably the best video out there explaining everything that truck ppl are into! The info and comparison is the best 👌

you REAL Canadians are the reason we LOVE you boys,GREAT videos ...FROM your FRIENDS here in the States

Best delete videos on RU-vid hands down ! Keep posting more mechanic videos.

I did a full delete with a +100hp tune and managed to get the same mpg, full delete with modified stock tune I went from 17mpg to 25mpg.

Thanks for the video. You covered nearly everything that I even care about. Good job!!!

I like how you did everything so that I can easily be put back and work when needed. In my area if you register your truck commercial there are no emissions at this point in time. I’ve been buying and driving older trucks just to avoid all the mileage and lack of reliability of emissions equipped trucks as well as I drive stick only. So picking have been slim. This info opens horizons alittle. Thank you.

That exhaust sounds amazing !!

I just found your channel SUPER helpful thank you. I wish I could get that exhaust sounds amazing

Another awesome video dude!

Awesome video it's great for comparison before and after 👍 God bless you and stay safe in these troubled times 🙋‍♂️🇬🇧

That's a much bigger difference than I ever would have guessed. Some of it may be deleting the exhaust gas recirculation valve,(EGR) and some might be restriction in the DPF. While those parts are off, you might see if it's possible to flow test, clean, or perhaps, just replace it. With the straight pipe exhaust, I could really hear the "whistle" if the turbocharger. The black smoke happens for the same reason, you feel the "snappy" throttle response. With the factory tune, it measures boost pressure, not allowing the injection pump to inject too much fuel, for the amount of air available to burn it. With the aftermarket tune, the pump squirts in the amount of fuel indicated by throttle position, regardless of boost. It smokes, until the turbo has time to "catch up". Don't use an aftermarket tune with the exhaust in place, because it will quickly foul the DPF. Using similar to a factory tune with the delete will eliminate the puff of black smoke, but, the throttle will feel more like stock. (sluggish, by comparison)You will, however, keep the good fuel economy, and the power. For the next experiment, try deleting the EGR, but leave the DPF and SCR in place. While the truck will feel "stock", it might gain the fuel efficiency, and, I think, will actually make the DPF last longer, and regenerate less frequently.

Great video! Answered all of my questions and concerns. In Ontario and considering a delete on my 19 3500 5th gen. I am sold!

This is something I’m definitely going to look into when I get mine

I have a 5th Gen. this is exactly he video I was looking for 🤘🏻 subbed. Well done imo

I miss my 6.7 so much. That's a nice unit my man

Very awesome, was informative and helpful to help me decide what I want done to my diesel Subscribed cause of the content 👍🏽

great video! love the truck and thanks for the conversions (American viewer)

5 mpg difference that is a whole hell of a lot for the lifetime of a diesel truck

Thanks for representing the reliability and fuel economy guys. We don't all want deleted trucks to roll coal. I would love to do this but I'm in the US.

I didn’t expect the surfer analogy LOL sending love from the Florida beach bro 🙏

Very informative videos! I just bought a 2017 cummins. I have been told to delete it. So these videos help alot. Thanks

So exhaust gases are bad for the environment but does the fuel efficiency increase of these deletes offset the difference?

Great video from a Duramax owner. I wanna get a Cummins 3500 for my future work truck. Thanks for the great content bro

Great honest interview. Well done.

*Great video and information. These really makes me want a diesel truck. Its getting the same mpg as my daily driver sedan.*

That is funny. When you made that right turn I knew exactly you were as I live in the next town over to the left of that turn haha. Glad to know you are local as my daughter is looking into getting a diesel and so am I.

So crazy. Its getting the same MPG as a 5.9 but with TWICE the HP and torque! The throttle response on stock 68s is so maddeningly frustrating. I love this, ahem, "small modification"!

I will say this is probably the best Cummins delete video literally there’s no goofing around bs it’s literally everything you need to know and you don’t have to deal with the nonsense

Nice channel man, subbed. I actually have a friend who had bought a truck with deletions and added them back on and then processed To make his truck super quiet with more insulation. To each their own, I like the loudness more. He had a charter buiness so he picks up his clients and doesn’t want them to get that trucking feel when bringing them to the docks, but he has a tune on it and said the back pressure is even better with the exhaust plugged up, does this sound right to you guys??

Wow sounded pretty bad ass exhust note with the deletes and fuel economy went up and throttle response 😁👍

14k subs wow look at you go ! Been here since like 300 haha

I have been your subscriber as i always liked diesels. I was a bit afraid going that route, but finally making up my mind to go diesel. We do about 2 winter trips to the NWT/Yukon and I am hoping i get the truck equipped to fight those extreme temps

great video man!

This video is at a higher level than in the past. With better content

It would be nice to test the exhaust gases before and after delete to see the difference.

Fantastic video. You brought up a lot of (like minded) points along with pros and cons. I don't want to roll coal, I just want to keep from trashing my engine.

Amazing video very informative 💯

Funny how the epa would rather choke up these engines and get 13-15mpg instead of letting them breathe and get 29-30mpg.

My favorite channel just deleted mine blown away with the results

I have the same truck but crew cab, I travel a lot for work and it’s also my work truck, on the highways and interstates in the states here I average about 22mpg at 70-75 MPH, and I haven’t even gotten the delete set up yet. Im excited now.

Love the way it sounds on deceleration

Good video. I have a 2011 2500 and it came deleted. So unfortunately I have no idea the tune, studs anything except for what I see and don't see. I love how it sounds like a race car! I agree about the smoke with anything newer than a 97 anyway. Sadly my exhaust brake quit and I'm hoping it's a censor or the actuator. I miss it! I'll be upgrading to a fifth gen after someone else puts 200k on it first. Then I can afford it! It'll be my third one.

I wish i never watched this. I can’t get that sound out of my head now.

Very interesting and informative. Thank you.

Awesome video as always

Doesn't your programmer / monitor allow you to adjust the tire size ? The Edge program I had in a previous truck allowed me to change when I did the lift and went up to 38" tires.

Good video bro. I did delete to my 2015 3500 6.7 last year and I'm super happy since, I'm making between 24 and 30 miles per gallon @ speed between 60 to 67 mph.

My freaking dream truck man

Thank you for explaining. We bought one

Sound of the truck on video while driving just sounds like a gas truck with flowmasters

That is my dream truck, color, wheels, mega cab and everything. I'd be so afraid to lose warranty though, then again I'll probably never be able to afford one new haha so a used one might be out of warranty anyway

That's awesome man! My 12v doesn't even get that mileage!

You DEFINATLY answered questions I had about deletes. Thank you for the Information. I would Love to delete my 2020 Laramie 3500 but here in Ca. there is definitely some steep fines to pay if caught with a deleted Truck......

I’m curious if you hand calculated your fuel economy to see if the truck gauge was accurate after the delete?

I own a 97' 5.9L 12 valve that gets ~25mpg average driving. Love the Cummins engines.

Awesome video,,i need this on my 2007 Dodge dually 6.7

I just ordered my delete and I'm also getting a tune and I also purchased a ram air intake system with some pipes, looking forward.

Can you enlighten me on the tune you used, as well as getting around the factory gateway firewall? I manage a government fleet and my scan tools wont even allow me to program my aftermarket tpms sensors..aargh! Great video

deleted my diesel two weeks ago, you put it just right when you said "its like a wave pushing you". im just running a 65hp tune and the fuel economy is unreal im getting 7-8L/100km.

I have a 2003 LB7, 30%, LBZ Sportsman regulator, stock/S475, 6-speed conversion. Longer gears starting with 1st is very helpful.

Love your channel

It would be interesting to find out which delete made the bigger difference and what impact tuning alone would do. Myself, I’d really like to turf the EGR. As for DEF, I see the environmental positives but once my warranty is gone I’m thinking delete that too.

If you don't do a quick learn on the 68RFE after flashing, you need to keep your foot out of it until the trans relearns. High rates of clutch failures if you pour the coals to it before it learns where the shift timing and line pressures need to be for solid shifts without slip.

Great thanks! Awesome job 👏 🏁

Good video thanks for sharing the miles per gallon that is very important to me very impressive mileage

Thanks for the video. Can you add a link to all the parts you installed please?

Had the same issue for the EGT temps when my 2018 truck was "exhaust modified". The truck needs an EGT probe now. I installed my EGT probe at the back of the exhaust manifold to work with the Edge CTS3. The truck will display 302F as the default temp when it can't read the EGT data anymore from the stock sensors. Great video!!!!

great video comparison!

Sounds so nice!

Have you got chance to delete any of the new half ton diesels? I have a 2020 Silverado with the 3.0 duramax. Just curious what it would sound like deleted.

I've always wondered if you were able to do an actual emissions comparison between stock and a deleted truck with a tune set for fuel economy, not to roll coal at every stoplight, and accounting for the increase in fuel milage would the emissions be substantially different? We know the EGR/SCR/DPF setup increases wear and tear on the motor and decreases fuel milage so I wonder if when you account for the increased fuel usage is all of the mandated emissions junk really making that much of a difference on the total emissions per tank of fuel or are the EPA numbers based purely on the instantaneous emissions. Does that make sense?

New sub. From south of weyburn sk. Good video thanks

Awesome informational educational video experience Y'alls God Bless Y'alls 🙌 ❤ 🙏

Need this ASAP!! In CA tho kill me, I just wanna roll 😂😂

It’s nice to see a straight guy driving these. Thanks for leaving the mirrors down. Nice truck!

That exhaust sound tho🥵

great video thanks for the info

I'll be looking for a ghost delete for my 2020 Ram 3500. I know the fuel economy would pay for itself pretty quickly

"I'll tweak these tunes..... I mean get them tweaked" lol

I just took my 2021 Ram 2500 Bighorn Crew cab, Cummins, short bed, 500 miles, Round Trip, down to Kentucky and back. I averaged 23 MPG, cruising between 65 to 70 MPH. It is completely stock with 46k miles on it.

Deleted and tuned my 2016 yesterday and oh my gosh what a difference in power, throttle response, and fuel mileage. Before it averaged 16mpg. On the way into work today it got. 23mpg. I have awoke a sleeping giant.

Thumbs up for not being an advocate for rolling coal! Good stuff bud

Imagine if the diesels came like this from the factory!!

Sounds great. Nice work.

Awesome vid

What was this customer’s ticket? Total cost of parts and install. Have the exact same truck. Thinking of doing the same but still hanging onto the warranty at 27k miles. Thx for the vid

Great video! I dont get the view the EPA has on def... Lets put something on trucks that makes them get worse mileage so they have to use more fuel. And then have to put stuff in another tank that will get spilled and has plastic drums they will just throw away and put more plastic in the land fills. Doesn't make any sense to me what so ever.

Just picked up a 2024 Rebel 2500 yesterday. Cant wait to do a delete on it but better wait for awhile for warranty reasons lol

Just picked up a 2020 with 94000km, definitely watching what you do with these trucks. Ok so why are we still using DEF when the engine is obviously more efficient without it? Keep it up! Mark @ Mannisto Cay

Would love to see a before and after on a new duramax. This video makes me want a Ram now. Would you get the aisen or the 68rfe. I like the feel of the 68rfe just unsure of the durability. Can it handle 75 hp tune long term? What about towing? Thanks. Great vid

Remember to measure at the pumps, ECU tunes can program the fuel usage gauge too, if they want to. I am a bit skeptical about the fuel millage, it is within 20% difference of my 4 cylinder stationcar for a truck that is twice the weight, twice the wind resistance and twice the wheel rolling resistance. The throttle response difference can easily be the ECU giving you 20% throttle instead of 15% throttle your foot tells the car to do. It could also be giving you 100% throttle shortly if you press the throttle quickly between 0 to 50%, that would explain the idle smoke. Try and test if the last 10-20% on the throttle pedal even does anything, it could be removed by the ECU.

Hey buddy I’m over in Ontario. fantastic video. I don’t know if I missed it but which tune did you go with? Was it Matt’s tunes? I’d love to do this exact setup but 4” exhaust on my 2020

Any difference in installing egt probe in block off plate compared to drilling exhaust manifold close to turbo inlet? Excellent videos, keep them coming learning alot!

Now alll he needs is a true manual drive

Great video question is it Worth putting a cold air intake and a 5 inch exhaust or should I just stick with a 4 in exhaust and no cold air

Love the info

5th and 6th are both OD grears. 4th is the highest direct drive. If you're in a long hard pull you should use 4th when you tune these trucks with the 68rfe.
