I'm gonna guess 340rwhp 338rwtq.Need to get a baseline before all the mods (although I do have the Corsa deduct 8hp?) Wednesday short shifter install form TPIS....
Will post the results for all to see
Dont worry about Corsa, it wont add anything if you are stock.
Stock i dyno'd 323rwhp 325rwtq. Although I truly believe my LS2 was not tuned correctly from the factory. A decent tune and headers popped me up to 363/361.
