clutch slip?boost leak?or what?

Heres my prob..scince i up my boost, when the car gets 2 bout 4000 rpm the rpms go down at same throttle then goes back up just not real slow but slow.. i know if rpms stay same but u start 2 slow down..its the clutch..but this is a lil diff...tx

How much did you "up" your boost. It sounds like at higher RPM's your engine isn't getting enough fuel. Maybe your fuel pump isn't ready for that boost? Just a thought. It's not your clutch. Clutch slipping is when the rpm's go up, but the car doesn't move, or barely moves. I know you said at the same throttle but I doubt it's your clutch...increasing boost doesn't directly affect your clutch. Are you in neutral, or trying to launch forward in first gear? (had to ask)

sounds like u have some fuel troubles...or tuning troubles

Well im only runing 14lbs and its a slow drop Then it goes back up and stays there..it only does it when i stomp on throttle..if i grad giv it gas its ok...ill jus keep turnin it down till it stops dropping rpms..Also still need 2 rewire fuel pump..Oh and i know inncressing boost doesnt effect clutch directly. But i am making more hp and i dont know how old the clutch is..

Oh and its when im driving....in neutral its fine..

i had a similar problem and it turned out to be a boost leak so if anything you should check for leaks no matter what.
