The owner of my local dyno shop has an 07 denali, i think, with this setup and his best time was 14.03 with just a CAI and his tune and full street weight. his only complaint is that he can't get the 2-3 shift to stick, it still slips and its holding it back.

I love the 6.2L, tuned an 08 and he went 14.1@99 with tune and u/d pulley on 22's and fiberglass bedcover in 80 weather, it will go 13's as it sits in better weather.

I have an 08 Sierra Denali. I have it tuned with a K&N and Magnaflow exhaust. Runs great and sounds good too. The only thing is you cant tune the transmission through the mail because the TCM is actually inside the tranny. So if you want to remove Torque Management it must be live tuned. So I'm waiting until I can make it to Houston to have the TM turned off. Should run a lot better after that. I'm also going to try and use the Pacessetters with a custom y-pipe.
