5psi
Ok I finally got my car running great. It no longer cuts out at 6k rpms. I can take her clear to redline
. But on my AUTOMETER boost gauge, it only reads 5psi if not lower. I dont know if I trust that gauge but it seems to work OK. The car runs pretty damn quick too. Whay psi should I be hitting (relatively). And what should I start looking at. I was thinking possibly a clogged cat, leaking line. I replaced some of the vac lines under the IC when I had it off. Or the turbo is just plain worn. Sorry if this question is rhetorical, but I didn't know what to search for. Thanks for the help,
Chris

"I was thinking possibly a clogged cat"
I take it he has a cat.
is it a 87-88 or 89-91? 87-88 run 5psi stock but with 3" downpipe and intake you should be running higher. I'd take a look at your cat.

A worn turbo will not just run 5psi. If the bearings are bad, then you'll know it because it will take forever to spool up..

sorry I should be a little more specific. I have an 87 and the HKS is the catback. WHen I put the exhaust on, I looked at the cat and it seemed to pretty clean(what I could tell). How do I test the cat? Also In first and second I will get about 5psi I never have enough room to test it out in the higher gears. Thanks for the help guys.
