I drove my new '91 TT last night after owning it for a month and a half and doing a bunch of maintenance stuff to it. It ran like crap and would not go into positive boost pressure at all. My Profec B was turned off because I haven't tuned it yet, but I should still at least get 7 psi or so right, right? I'll start diagnosing the problem tonight... Post on here if you figure out your issue and maybe I'll start looking there on mine.
Later,
