Depends on the load on the engine and the fuel your using. Under normal cruising and idle, the ECU should maintain ~14.7. Under WOT (91-93 octane) you want to aim somewhere between 11.0-11.5, depending on how your car likes it without knocking.

Thank you for the help. I only run 93 in my car

Lucky bastard We only get 91 down here, the wife's Mazdaspeed hates it. That's why my Talon only sees E85...
