I'm not an expert - but surprisingly the launch control system works pretty well, even adding ~80 wheel horsepower with the stage 1 tunes. I think the traction control systems detect wheel spin and add/pull power accordingly, regardless of peak power figures. My 60ft times are the same with a stock tune and a stage 1 tune, buy my 0-60 times are much better (~4.1 stock, 3.6 with stage 1)
