the symptoms I'm getting are mostly when im going uphill around 50-70mph the boost gauge goes up to where its supposed to but the car wont accellerate . the boost stays up and the rpms stay the same but no speed increase, and it only does this sometimes also it usually cuts out for a second afterwards

If you're reading full expected boost, you're getting it. The MAP sensor is measuring what'* in your manifold after the supercharger. There'* nothing wrong with your BCA or BCS.

If it'* cutting out, you're back to the basics. Fuel and Fire. I strongly suspect a misfire. Those are the conditions they'll be most obvous in.

had a scanner hooked up to it and no more misfires( tested while driving) was thinking would a fuel pump on it'* last legs do this? again only seems to happen when uphill also tested the coils and they tested in range. could one go out and only show when going uphill?

A scantool will only show misfires under certain conditions.

If you suspect fuel, don't you think you'd notice an issue wide open? Check your fuel pressure to satisfy your curiosity, but I'll stick to you having a misfire.

how can I tell if its a misfire the tool is missing and what could cause it? new wires plugs pcv etc the only thing left is the coils right?

well the fuel pressure is about 42 at startup and then when going uphill its about 50 then it drops off to about nothing and the car cuts out then it kicks back to 50 then nothing again? does this sound like the pump? also the motor mount seems bad the engine is sagging and the little piece that I think should be centered is sitting at the top of the motor mount any ideas?

well the fuel pump was shot and the other rattling was a bad motormount and now the radiator is leaking every once in a while so its next

Which mount was causing the rattling?

passenger side front it was sagging and hanging up on the cv or whatever its called whenever it was under alot of tork gone now though

There is no mount on the passenger side front, and no mounts anywhere near a CV.
