OK, life is good again. 20psi of fun. Plug wires were grounding to the
block. So scince I am borrowing a friends set of wires, do any of you guys
have any experience with Nology wires over stock?

Hey Ben,
Ya new valve. funny thing is i still pull 20 psi. i keep wondering if timing
is being pulled somehow. there is a dramatic power difference from 10-12psi.
falls off. Smells like i am running rich with the windows open and driving,
i keep wondering if my fuel pressure regulator is bad, dumping fuel after 10
psi. all the plugs look good, O2 is new and white when i pulled it. The only
hose left un touched is the upper intercooler hose and the turbo intake
hose. The oneway breather is shot, i am getting a multi sensor tommarrow. do
you know what the coolent sensor onthe back of the head does? or maybe the
altitude senor is the culprit?

I'd be looking for a small leak in one of the intake hoses.


Also, if the bypass valve is remaining open, you won't be able to develop
full boost.

I can no longer make power above 10 psi, kinda bogs down and makes a heavy

fluttering noise, rough idle too. All vaccume line have been replaced, lower

turbo hose is samco, new o2, clean isv twice now, new distributor, newer

incercooler, new vaccume line in ecu,  bpv works,  new boost gauge line,

waste gate and hose is good, manual boost controll (n75 is still connected,

zip tied up). Any thoughts or suggestions?
