If you do a search you will find that many people have supercharged Denali's on here.

I haven't taken my to the track yet, but I have done some test runs using a G- Tech as well as two other performance meters and I did 4 runs and they all were within a tenth and the best was 12.43 @ 108.64 mph so with some adjustments I'm hoping to go low 12's

Mods and times in sig. What boost are you running and are you AWD or 2WD? I wouldn't completely trust G-Tech times.

With similar mods to you I got around mid 12's in a 2008 SD with AWD.

8 PSI through a whipple, ARH headers, 3.73 gears, 2800 stall. Even with the 12.6 runs the 6L80 was acting up a little and missing shift points so there is a potential for better times for someone who beefs up the trans to handle things better.

Yup there are a bunch. Where are you from? Why don't you have a little fun with it and bring it to a track? It's the only way to know what your truck will actually run... too many variables otherwise.

Thanks everyone and I'm running 8 Pounds of boost and its a 2011 Sierra Denali AWD and I agree the only way to know is to go to the track so that's what I'm planning on doing once the tracks open
