All good advice, but ive had to dig deeper, may not have the balancer tightened enough against the reluctor wheel.

3200 PI actually. Ive always had better luck with several cars flashing the xonverter or leaving right off idle. Regardless, that doesnt explain the lack of mph. Yhe car is down on power and there is a reason i have yet to find.
