make sure the

boost control option is turned off (its a japanese character)

as well as

the idle motor option which i can't remebre off the top of my head what its called.

its in the MISC menu setting.

if i get a chance to grab the commander from my friends car

ill take picutres with screen shots, also did you email me?

ill be happy to walk you through the propper correction procedures.

i dont like the % correction on the commander, its doo doo.

Actual injector change is better.

PS. 13:1 AFR is not too lean. 14.7:1 is just fine and I frequently tune turbo cars to 15.1:1 afr on 91 octane for part throttle adjustment.

Soundsl ike an issue with something else?

Another thing I have noticed is overly high fuel pressure at base

Happened with a friends car recently, the person who tuned it before me failed to check base fuel pressure, the car was getting horrible gas milage and response was stunted drastically as well as low end torque although the AFR's were in the safe zone.

FP makes a difference as well.
