Only the 6.2 has the 8L90. The truck is quick. It'll do high 13's bone stock.
I drove this one once and it's just got a canned tune and it flat hauls ass for a stock truck, pissed me off it'll flat eat my truck for lunch.
Opinion on the 6L90? Cost to rebuild?

I don't think my '16 6.2 is quite as fast as my LML tuned by Rob, but it's not tuned yet.
I do miss the boost on the top end though. Going to have to do something about that..Dropping a Whipple on this will put it in the mid 11's.

:roflmao:
Did they upgrade the 6l90s in 10/11 then? I drove a 08 that had a manual shift mode guessing it was a six speed that shifted like a turd compared to the 2012 as I've driven.
I missed out on the truck unfortunately it sold yesterday. 10k for CCSB 4wd work truck in nice shape.

I know that the '12 and later 6L90 had better parts. Can't say when the better parts started being installed.
Jason Nichols ( LBZrocks ) has an '09 CTS-V that runs 10's ( 725hp ) and his early 6L90 is still holding.
I know that the late Camaro guys running big HP are switching over to the 4L85E because the 6L90 won't hold.

I need to shed about 1000-1400 lbs off my truck and take those 35's off and it'd probly be more spunky. Changing the fuel filter every 3-5k would help too. Just changed another one today with 7200 miles on it and the fuel wouldn't even drain out and truck was holding gears and not shifting prior to changing it.
Where the hell are you getting fuel at so I know NOT to go there? I have a 19 micron pre filter for my lift pump and the stock filter at the engine, and even at 10k miles both look new when I cut them open, so I'm going 25k on them this time.
