Slipping...please help.

Alright here it goes, when Im getting up in high rpms and its boosting around 6-12psi it feels as if the car isnt moving forward as fast as it was. Its like its in neutral for a couple of seconds and then itll catch again. My buddy checked it out and he couldnt figure it out. We looked for vacum leaks and checked the bov for any cracks, found one and fixed it(small). Drove it again and same thing. Hooked up a boost leak detector to it and it checked out fine. Is this considered boost creep? im running with EVERYTHING still stock as this is pretty much my baby to me. My buddies think this is a form of crank walk in the making with it doing this slipping like feeling....i just think it may be the waste gate? But everything is stock. Also EVERYTHING(except motor) was replaced about 3,000 miles ago.

So say im going 55 in 3rd and im around 4500rpms when i start getting on it, it starts to pull and just suddenly quits but keeps spooling and building boost.....but NO power to the wheels .

Thanks for your help in advance.

It might be your clutch slipping. I have the same problem but I pay attention to my rpm gauge and notice that it would stop gripping and the rpm would like climb up and I have to release the gas and step on it again to get it grabbing again.

BTW....I notice this when I tried to launch my car and in 3rd gear as well. It does what you describe where you feel no power to it.

exactly! i had my buddy up at the shop put in an exedy 6 puck about 4 months ago and i never have grinded or anything like that. it just started doing this powerless feeling but the rpms dont drop at all. i have already made arrangements to buy my buddies built 6bolt cus of this damn problem . but i still want to find out cus it wont be done for another 2 months...
