the help of one of our more learned members (Seb at SpecialtyZ), he suugested that it sounds like your timing belt is off a tooth or two. This was before I even mentioned about the recent 60K service. I just don't think that your DPs or TPs could be plugged up and you could make the kind of boost that you are. And if you could, you'd see higher power numbers. Seb stated that in many case people forget that there are five points that must be lined up: the four cams and the crank, and that people frequently forget to set the mark up on the crank when doing the belt. That diagnosis makes sense, given your symptoms. Hope that is of some help, and thanks to Seb for letting me bother him on his day off, Mark
