Remember all these other people "including Z1) throwing dyno numbers around dont mean squate. Every dyno is different, IMO most places inflate numbers to make customer happy. ( 341 WHP NA 370 Sure)Dyno's tell you almost nothing other than your tune is safe cause you can get the car up to 120 MPH for tuning and not worry about crashing. You wanna see what your car really makes hit the track and take you 1/4 times and MPH with you curb weight and figure it out. If you happy with the way the car performs on the street then be happy, chasing dyno numbers will do nothing other than upset you casue no ones is the same.

BTW I have every bolt on and ECUTEK tuned by Seb and we all know how good he is and my dyno told me 314 "uncorrect". But thats just want a machine told me, I will compare to my track numbers last yeat of 13.5 at 105 MPH (3800 LBS) X sedan.
