Well I'd llike to have 550+ rwhp because i have such a damn heavy truck. I know I need to upgrade to a 4l80e but in the time being I wanna figure out how I can get to 550+ from my 5.3 or If i should just buy a package lq9/4l80e from a junker.
2007 GMT900 CCSB 5.3 VTS2300 Twin Screw Supercharger, Doug Thorley LT's, True 3" Duals into Dynomax Race Bullets, Nelson Tune, 4L80e w/transgo HD2-D, Truetrac, 4.10 r&p
Need list: Stall, PLX 200 for my crappy AFR, X-pipe, GM 20's.
