try adjusting the rod behind your clutch pedal...it may be engaging too far out

ok, i changed the saprk plugs and that didnt do ----, so im guessing its my clutch, so is that why my boost keeps going down or is there another reason, im guessing the clutch is sliping so there is less of a load on the engine and the turbo isent staying spooled up, does that sound like the problem? has anyone had a problem like this before?

Re:questions about clutch or spark plugs
 

sounds like it....and you tried adjusting it (the clutch that is)?

adjust your wastegate for more boost and see what happens. how do you know that its actually at 6psi, how did u test that?
