I went from a 2018 CC Z71 5.3 6 speed to my current 2019 CC 2.7.  
I averaged 17MPG in the 2018

I currently average 20.5 MPG in the 2019 2.7

If you’re looking to save MPG and don’t have a need to tow, the 2.7 is a great.  My 2WD rides like a Cadillac, after the 8 speed jerks from 2nd to 3rd.

I have about 2700 miles on my 2.7 and it’s been back to the dealership once and likely will go back. At first I thought it was a transmission issue but it appears to be an engine issue. It skips and sputters intermittently. All they did the first time was reset the ECM. Frustrating.

Are you easy on it? I'm wondering if owning a turbo is like a woman you got to open her up every now and then and ride her hard, and she will treat you better in the long run.

So you own People...   You should really reconsider the words you use on a online forum.

I can get over 20 mpg on E-85 at 60 mph with a 4.3 V6. Truth is I can't treat is bad enough even in the middle of winter to push it down to the 'national average' 17 mpg even on Ethanol.

Hey guys, have had my 2.7 for 6k miles and it's been good... But is it normal for this engine to rev pretty "loud" on accelerating from a stop? Once cruising the turbo accelerates it with a quiet whistle, but going from 0-40 sounds like it's taxing the engine for a normal acceleration.

Yeah it's a 2.7L engine trying to get a full size pickup going.  I love my 2.7L but yeah it sounds a little taxed from a stop.  I don't think you have anything wrong.  With a CAI I've recorded 6.8 second 0-60 not too shabby.

Thanks for the feedback. Which CAI did you get?

I need to find one and test drive it.  Not that I would get it but curious as to how it performs.  Seems like it does really well.

I bought a 2021 GMC Sierra 2.7 turbo I’ve had it for 6 months and I already put 18k miles on it she runs brand new still. Sometimes i regret buying because she’s a four banger but i’m telling it pretty fast for a truck. I think i’ve hit 0-60 in 5 seconds before (usually around 6-7 secs) and that’s surprised me. I wish there were mods and stuff you could do to them to make them even faster

I love my 2.7L but you never hit 0-60 in 5 seconds.

This is very true.

      upgrading speakers on 2026 std cab WT...

      By bwiese · Posted

      I don't wanna do major surgery/upgrades, behind-the-dash work, add amps, change radio etc. on my '26 std cab WT. On the WT, it has the base 7" IOR infotainment setup, and only two speakers (doors). Since I listen to classical, looked around for speakers that do well and dug thru reviews. Two-way speakers were found to be better than 3-way. So I've ordered a pair of  Infinity Reference REF-9632IX 2 way speakers.  [These may  or may not have been discontinued / succeeded by the 3-way ...9633 ones.]    These speakers are lauded for 3 ohm and 94db sensitivity spec so they'll work well for ordinary base car radios without amps and offer better performance (quality,  strength) than  default base paper-cone speakers. They'll be installed in a few days and I'll let y'all know what I think. Bill W San Jose

      Thanks!   Changed out the rear shocks today to Bilstein 5100s.  So far feel much better. The stock Rancho were wore out.  Lots of heavy hauling (2 moves, home renovations, etc).  Next up is new BFG tires Monday.  Cant wait the current tires have little to no wet traction and are super loud (hum)

      Correct way to service 2024 l8t allison trans?

      By Chuck FB · Posted

      How about I just point to the factory pans stand pipe little drain plug and claim its a pan with a real drain plug !. I just couldn't swallow the fact that a Dorman pan which at this point is probably the only pan out there that fits the gas version truck cost that much up here in Canada so I decided initially anyway to skip it and see what I thought of pulling the pan method and down the road if I felt inclined enough then I would either install a drain plug kit in the factory pan if there is enough room for it, or have a bung welded onto it, or put an aftermarket pan on. The thing is if the pan is not pulled then the magnets in the pan can't be inspected and cleaned or if wanting to change out the filter. However of course it certainly would make the job easier to be able to drop the oil first before having to handle the pan if dropping the pan that go around was the goal.    I knew a guy locally that was doing custom field spraying years ago with a pickup pulling a ground driven sprayer, I believe it was a GM pickup with an automatic trans. He had a drain plug in his pan and would drop the oil out of it once a week and top it back up through the dipstick tube to keep refreshing a portion of the oil often and that made the transmission last far longer than had he done nothing. Soft fields pulling 500 gallons of water at the start of each mixed up sprayer tank batch and in low range sucking along. I imagine he got some tips from other custom sprayer outfits doing the same thing at the time and learning from their blown up tranny mistakes. Transmissions then had no lock up converter so would cook the crap out of the fluid slipping that much and it would not have been synthetic fluid either.
