Ok on my 2000 procharged GT I cant make any boost it stumbles when i try to make boost.If im invacum my car runs fine. I've changed fuel filter, fuel pump, plugs, cop's checked! fuel pressure @ 30-40psi. I have found oil in the pipes all the way upto the throttle body. Could it be my MAF?? if it has oil on it? Any help would be greatly appreciated.
Thanks.....

Sounds like you got a leak somewhere..... Something is loose somewhere....

Well i will check my lines for leaks and see whats going on. Any other ideas would be greatly appreciated

Your tune also.... could have taken a dump.....

if you have oil in your tb i would take off intake tubes and check in the supercharger you may have blown a seal....

Most likely your tune. Have you switched the MAF? And is your tune set up for your maf.

When I had a tune on the car setup for a different maf, it just flooded the engine with fuel anything over 2k rpms.

Well I dont know alot about S/C's but still learning...this seems like it would be the problem, or the tune.

Did you have it tuned?? Mine ran like crap until it was tuned.

I'd start by doing a boost leak test.. Go around and check all of the couplers to all of your all of your intake plumbing... Then, if you think everything's good there, then start checking things like the throttle body gasket, and other things like that...

+1 If it's not supercharger oil in your piping then it must be engine oil. If it's engine oil then check your compression because it probably means you have excessive blowby.
