2.7 Turbo 4 Fan Club

I would love to see someone come out with a tune for these engines. You would probably see an extra 50-70 hp and tq at least.

Hello, started an account here because I read through this thread and found it very informative.

Here is my question if anyone wishes to reply or suggest anything. I plow my driveway (just mine) with a 2010 Silverado 4.8 with 120,000 miles. It does a great job, even where I live in Maine where we can really get buried some winters. I kept the 2010 for a plow truck and recently purchased a 2022 2.7 Custom which I absolutely love so far with the 600 miles I’ve put on it.

After driving it for a bit now I don’t see why the 2.7 wouldn’t be a good option to use as a plow truck for just a single drive way. Everything I’ve found stated that the 2.7 has more HP and more torque even at lower rpm than the 4.8. Does anyone know why this wouldn’t be a good idea to plow snow with?

I’ve scoured the internet and only found one forum where someone put a plow on his but after the initial post and conversation, it hasn’t been updated. Some plow sites say that they don’t have options for turbo engines (eco boost or 2.7 Chevy), but some do. For reference I have a BOSS HTX straight blade that’s about two years old, basically brand new.

The only thing that some people mentioned is that the plow may block some air flow that may effect the turbo and cause it to go into limp mode.

I’m no expert so any knowledgeable comments to this would be greatly appreciated if there are any other snow plowers lurking on here.

Also, I’m averaging 23.5 MPG since I set the trip after leaving the dealership. I’ve seen that that is a common topic on this thread.

I also would like to see a tune. My interest is more in fuel efficiency though. I think major improvements could be had with only minor reductions in driveability.

ECE you have shutters on your truck which are closed most of the time in the winter, so i dont think a plow would hurt it

The air intake is located upper left hand side ( drivers side under hood facing up). Turbo air flow restriction NOT A PLAYER. I have pictures on this site of my trail boss buried in snow up to

lower head lights and doing just fine.

I don't plow but live in high snow area at 9000' msl in Southern CO. The front suspension is plenty

tough to handle a once a week snow plowing.

You will need counter weight in bed as like majority of GM trucks its sprung too light in back over locking differential for my 2022 LTD

Trail Boss. I ended up needing about 720 lbs of sand tubes @ 60 lbs a piece.

For a Custom it MAY not be stiff enough in front unless you have Z71 package or better shocks etc.

Off topic : All the sudden this site is wrapping wide on display is that happening to others or my browser?

Yep, been doing that to me for a few days now.

Good news on this. It looks like trifecta tuning is working on a tune for this engine. Check this link out.

Sweet! I had looked a while back but not recently. Thanks for posting.

When I got my truck the dealership filled it up and then let it idle for 30-40 minutes while I did paperwork and then they did the walkthrough to show me the truck and to let the Onstar rep try to sell me a bunch of stuff via the truck's internet connection. That was neat I guess and probably a real moneymaker for GM but a waste of fuel. Initially the truck reported 10.6 mpg because of that. At 350 miles on the odometer it's up to 15.6 mpg.

Just did the first fill-up. I had a $1/gallon discount so it cost ONLY $93 to put in 21 gallons of 87.

My driving is at sea level, and is a 50/50 mix of city and highway. But the highway can be pretty much a parking lot at times. I think I will be lucky if I get even close to the numbers some of you mention. I will be happy if I am north of 18mpg per tank.

God I hope this is good. I think there’s reliable power to be had here.

The great thing is this will be a native tune and not a piggyback like other ones.

I’m afraid to see the cost

I'm afraid to see how they get through the encryption. I will believe a real tune when I see someone else use it! LOL Being able to actually change parameters in ECU

and not just tricking nearly external components like E throttle has me believing it when I see GM approve it.

Aren’t there tunes for the 3.0 duramax?

Well they were the first to crack the new corvette ecu. So I would say this is the real deal.
