I have a 99 cobra convertible with bbk x-pipe, flowmaster exhaust, hypertech power programmer and 4.30 gears and a stock 350z walked me from a roll. The first time we went from third and he got me by about a car length the second we went from second and he jumped out in front and held about a half a car until the end of third. I know these cars are respectable but really expected more from the stang with these mods. I just picked up the car three weeks ago and it was stock then so all mods are new. Is this a usual outcome for a race like this or is my car unusually weak? I know the z comes stock with 287 hp and is lighter than my car but they only run low 14's stock, this is really not that fast. Any suggestions?
