Alright, I was at the track, did a few runs at 8 psi. Figured it was running well enough turned her up to 14 psi.

1st gear felt fine(i think) 2nd gear it bogged and sputtered, coasted down the track. In the pits I couldn't find anything wrong, no intake leaks. Car is fine under no boost.

I drove it home this way (3hr drive) doing 140km/hr no problem(passing was hard to do while trying to stay out of boost).

Can't find any intake leaks anywhere, car is fine until you enter boost and it falls flat on it's face. Still seeing 12-14 psi but with a/f's all over the place(seems like it's discustingly rich though, and misfiring).

Any ideas? I've checked all the vac lines(not many to check, no vac rac or anything, fresh plugs.

 

Are you reading the a/f numbers with a wideband? What are your settings on the AIC? What size injector(s) is it controlling?

 

AIC is turned off right now, eliminating as many things as possible.

Readings are with a highband o2(greddy o2 sensor & gauge kit).

 

Bump....

Checked turbo, has a bit of back and forth endplay, about 1-2mm and i found oil in the inlet of the turbo too...
