Ive run my car on a dyno 3 times. The tuner who installed it gave me a chart that said 460 at first, then when I said it wasnt "that fast" he "retuned it" and gave me another run that "made 494tq. I basically got laughed of one of the other forums for that one. So I went to another dyno and watched the run and made 430tq on a DYNOJET. The first runs were on a Mustang dyno. The car runs really smooth I just like more throttle response. I didnt like being lied to about the numbers. Plus I didnt realize he didnt change out the fuel pumps. Now I dont trust the car. Ive run n2o for years and want to go back with that.I guess Im just old school.
When I asked about them about a month later he said that the stock pump was good up to 425 hp.
