Not may, can. Listen, I believe you trapped 107. I don't believe you did it with the few bolt ons. Not a Stock GT. I believe that you do not know what has been done to your engine in the heads. Racing on the street does not compare to racing at the track. You cannot compare times and results, it is very different.If you can sometime, get a dyno and post numbers. You will put a lot of this stuff to rest. Finally , racing to 130mph is STUPID, unless you can do it from a stop, at the track, in the quarter.
