Default RE: ud pulleys = bad?

I had the MAC piggies and it started throwing misfire codes after about 80 miles. I think that by moving the stock balancer outward, it throws off the center of balance and the sensor picks up a vibration or something. That's my theory, anyway. I bought Steedas and no longer have that problem. Oh, and once the stock balancer is mated with the crank piggy, they are mated for life. I cannot separate them so far. Then again, I have not really tried either.

If you have a stereo system in your car, buy a bigger amp and you will be fine. Buy steeda's, They are the best out there. I've had me up pulleys on for months now and not one problem at all. Steeda's are also SFI approved.
