As it turns out, my hoses are in good shape and my boost seems to be fine. the rev'ing is the clutch. Someone please explain why the clutch slips so badly in gears 3 - 5 but i can engage the clutch with no problem in 1st gear and go full throttle through first and 2nd through the power band. i consider myself easy on clutches - drove a VR6 to 160,000 miles no problems and a wrx to 130,000 w/o problems, yet my GT has 130k and seems to be shot (albiet a fair amount more Hp).
