absolute 5.3 stg2 g5x2 now added 90 lsx previous numbers 458hp 414 tq on an 02 c5 AS stg2 5.3, g5x2 lg lts. Added an 90 lsx and ewp numbers were 478hp 421 tq. Removed the mufflers for a run and pulled 483 hp and 427 tq. The car had to be retuned first pull only showed a 2 hp increase which scared me to death after spending 2 g's on the intake, tb and ewp. but after tuning 18 hp, I was hoping for a little bit more out of the intake and pump but all in all 483 hp is very stout. next year stg2.5 ls6 heads

Where did your hp and torque #s peak?? i have a G5X2 and 5.3L Stg II patriots and im wondering if its even worth ringing it out to 7K, the car actually is quicker shifting at 6400 or so... Never had it on the dyno yet though.
