RE: another little problem
Have you ever done a boost leak test?

Boost leaks can often cause all kinds of weird things. Check all of your vacuum hoses too. If that doesn't help let us know.

RE: another little problem
A boost leak can happen at anytime. If you're still using the clamps that came stock with the car, those may be losing tension. Your sidemount could also have a hole in it. The TB could have a leaking BISS, but most of the time, the piping just slips.
A boost leak check is never a bad thing to do multiple times. The bucking that you're describing sounds like a leak to me, whether it be vacuum or actual boost leak.
Do you have a CEL or any other indications of something being bad?

the gas im using is 93 octane. and no i have no check engine light on. i will do a boost leak test just to be sure but i dont thank that is the problem, otherwise i wouldfeel a drop in power. i will also check all of my plugs and wires just to be sure. anything else i should look at.
