with 12lbs of boost I would also work on the tranny LOL.
I ran mine last year, nothing special my best was 14.79, not to bad for a 5500lb truck.
Yeah, the 4l60 isn't gonna last long with anything over 400 horses, I had a 99 tahoe on 35's with a 6 inch lift and a whipple at 9psi with alky injection, I smoked that tranny within 2 months of putting the blower on. Green over at Quality transmission built me a bad *** tranny, that thing used to break the rear loose shifting into 2nd, it was a hard shift lol.
