I'm not a turbo guy, but I know you want to be slightly "rich" due to fluctuations in the AFR. Something like 13:1 - 13.5:1 would be safest since it will end up changing from idle to WOT.

Getting an EMS and full tuning would be best rather than just using a fuel regulator. Hondata, Neptune, Crome, AEM, etc.

EDIT: Moved this to this Turbo section.

You have a wide band O2 sensor right?

Nooooooooo, you don't want that.

Target AFRs for FI are in the 11-12:1 range. 12:1 for mild boost (<7 lbs), 11:1 for higher.

Are you tuning this yourself? No offense, but if you are asking what AFRs to shoot for it doesn't sound like you should be tuning your car...

Oh wait I had that backwards!

Yeah you want it slightly rich so less air to the fuel. Too much working upside down for me today, the blood must still be in my head.

His signature says "retune" 11 psi. I'm guessing it messed up at this boost level. Hopefully he has a wideband and an EMS.

11:1 is a good number to shoot for. But ... the a/f should change when boost kicks in as compared to vacuum.
