My friend just bought a 2000GT with a procharger.. He says it starts missing from from around 4500-5000rpms +.

The car has a fuel pressure gauge, but it bounces around... What should it be at at and how should it act?

Any other ideas on what it might be? The car was put together a few years back before SCT was real big so it was tuned with a chip.. It has a delk sticker on it so we imagine it was tuned there...

Spark plugs might be "blowing out" at higher revs--replace 'em and close the gap up a bit to 0.040" or maybe even a bit less...

My plugs are gapped at .035 and my fuel pressure is around 42psi at wot, and stays there. If his is jumping around at wot thats probably why its cutting out.

Yep, sounds like spark plugs gapped wrong or fuel delivery isues. Best he gets to a decent dyno tuner ASAP.
