Got my UR Pulleys put in today and also regrounded my MAF. I haven't noticed too much difference yet with the pulleys but I haven't really unleashed the fury with her yet. That and it seems that my PS pulley is too narrow and has been eating at the edge of the PS belt. So it's running on 3 1/2 ribs. I don't know why, maybe the person who had the car before replaced the power steering pump and got the wrong size pulley? Has anyone seen this happen?

Can't wait till my my ECU adjusts to the pulleys so i can take my car our and see if I feel a difference. As for the MAF, it was at .012 and now .003. I found that I have less hunting now than i did before.

With pulleys your not supposed to *feel* any power increases. From what i understand the power is added very linearly which results in better Dyno resluts and track times, but not NECESSARILY a better feel.

You're right. There is so surge of power, but I do notice that I don't have to put the accelerator down as hard to pick up speed as I had to before. Overall nice mod I think.

You might notice the engine revs more freely.
