well first off all i have a 97 gsr, today was my first time dynoing my car, it was a mustang dyno and my numbers were 147whp @ 7500 and 107ft/pd at 6500, and it was a very cold day, so corrected to 25celcius it was 139whp, and my car is stock except for a comptech ice box, i heard that mustang dynos read less than dynojets, is this true, and if so how much could it be if it was on a dynojet
