I thought they had an inherent problem with the boost gauge line cracking at a cetain point, causing poor reading of boost.

Edit: PM Onyxz32, hes supposedly the local z guru, but i dont know how much he knows about z31’s

stock gauges arent exactly accurate…but check over the ic pipes and see if everything is as it should be. 3.5psi as opposed to 10 (guessing) is a pretty big drop to be just a vaccuum line or two. how much of a power loss is there?
