I did a boost leak test last night and no leaks at all. I replaced the throttle body shaft seals about 6 months ago. I have tried just about every tuning trick i know of and still does the same thing. Im stumped. The fuel trims are short -0.04
mid -1.02. Fuel trims look good. It only happens on part throttle coming off a light. When i am very very light on the throttle it will only go to 11.0 afr. Something seams like something its adding fuel somewhere.

could be tons of things, but are you aware the trims can read dead on and be way off? not saying yours are.. just throwing that out there. maybe something was adjusted you're not aware of, acel enrichment tables, or locked into open loop in certain areas.. and so on.

my recommendation to you would be to start with a new rom from scratch and go from there if you're the only one tuning the car.

I started from a fresh rom. I changed the open loop throttle load high/low raised them up a bit. It helped but still there. It dont go as rich so i may be on the right track. Im going to play with it in the next few days and see if i can get it tuned out and i will post back on what helped.
