thanx for the reply, i got one more question....
when i removed my head i noticed the metal line coming from my wastegate going up over motor between valve covers has a large hole in it.. i cant tell if the previous owner did that on porpuse or if it got rubbed thru, is that a problem and if so where can i get another line? i thought about just cuting it and putin a rubber hose there to connect it but its rite next to the manifold, thought the head mite melt it... any suggestions?

you will lose boost through that tube if it is cut. that is what opens the wastegate.

My Autometer boost didn't come with it either.

It's also been on there for 80K and still working fine and completely silent. That said, I wonder if Dave was talking about electric gauges? I know my electric fuel pressure gauge makes a racket, boost pressure might be the same deal.
