I just got through my 500 mile break in period of my ATI P1SC unit. I'm getting some vibration that seems to be coming from the engine and not my wheels. I only think it's not my wheels because I just had them re-trued. I look at my stock crank pulley and there is 0 wobble from spinning off center. ATI gives you a big *** aluminum spacer and to use with there pulley. There pulley is definetly spinning off center. It looks to be off around 1/16-3/32 of a wobble. Is that enough to overpower the stock dampner? In 3rd gear @ 105 there is actually a vibration resonouce that's audible. Any ideas?
