Mine revs up to 7250 indicated on the tach. I would think this is actually 7500 but the tach just hasn't had time to respond. It is still not right, but running much much better. It feels like I have gained maybe 25 hp over stock. I know that is not good, but It doesn't stumble at 4000 rpm anymore.

I have called vortech many times, and the few times I actually talk to somebody, nothing they suggest really helps.

I hooked it up to a scanner the other day, and one of the banks is running richer than the other. Not sure what that means.
