There is a SC (stillen), but no one will tune it. It comes with a piggy-back ECU (PCM) and to make things worse, the transmission computer (TCU) is in the tranny, so no adjustments can be made to it.

yes Buzzkill is right...the only tuning for the SC is a Stillen piggy-back unit, which leaves much to be desired as it has blown several motors, but that also is due to some installation issues, even the guys that got transmission upgrades with the SC still arent doing great yet...basically all we have for aftermarket is bolt-ons, tune, cams, and just recently a stall convertor that cost a few grand

was the 2008 Denali a 6.2?? or was it a 6.0...i know I raced a 2008 Denali at the the track and he ran 14.7 with just a tune....the 6.2 is the 09 right? man those are serious numbers, i'm liking that 6.2L option on those trucks....is it a good transmission that has been paired with that 6.2?

08 Denalis have the 6.2 as well as the new 6 speed 6l90e that is supposed to be extremely stout. The 08 chevy's have the 6.0 and 4 speed automatic.

o ok thanks....i know a guy that had a Titan got a Denali and was running high 13's with just intake, exhaust and a tune....the other night i was at the track and that same Denali that ran a 14.7 with just a tune was there (i was runing 14.5 at the time)...me and him happened to line up and i thought i was gonna destroy him because i'm a bit faster now...well he must have done something new cause he was right on my rear, think he ran a 14.2 to my 13.9...he must have got an intake or something cause i didnt hear an exhaust...theres actually a video on you tube of me racing him, here it is, i race the Denali at like 2 mins 23 seconds in, but its horrible video cause the camera guy sucked:

and that first race on the video is me against a Z28, it looks like he smoked me from that Video, but he ran a 13.93 to my 13.95 so it was pretty close, later that day i ran the 13.85 which is my best...i need some Nitrous
