You guys are right. Dyno numbers are different. I went to do some runs on the first dyno & disappointment.

That explains it.

You have bigger problems than what your car was doing on the track. You lost a ton of power. Maybe time for a retune.

Re: more power= less mph

guess that guy has a hi reading dyno and i guess the low mph actually came from less hp than he thought. I wouldn't think that the 210whp would lose 4 mph glad that u figured it out.

And get that thing retune with a good tuner.
