How did you raise your FC that high? Did you go with a Lex/550 setup? If you did, do you have a fuel controller? The lex/550 setup will run very rich without tuning.

Strangely the car is almost all stock. Stock afm, injectors, the whole car... besides the K&N intake and cooleeze catback. I was surprized it would run at 15 psi too. I thought I was supposed to hit fuel cut at 12-13 psi.

I am just using a MBC, spring and ball style.

i could run 14psi without messing with the stock afm. then i could run about 15.5 when i backed the screw out of the stock one. without hiting fuel cut with stock injectors.

black = rich and thats what supras run. i have my own dyno from back in the day that shows the a/fs take a dump after 2750-3000rpms at a sub 10.0:1. get an afpr and take it to a dyno and you can lean it out some.
