fully built 04 sti new built motor.
need some help my tuner has flaked off on me with my 1500$ DEPO for tuning my car.
so the problem I am having is.
with no vac leaks from the manifold the car will stall out coming out of boost and to idle like rolling to a stop sign and does not hit the target AFR it was tuned for and runs lean.
I pull the vac line for the break booster (yes I lose the booster but I have big legs and big breaks) it idles find does not stall out and hits target AFR. so my question is what would be the best thing to adj???? I have the pro tuner program for my access port and the base tune maps the tuner did do before he took off. please help.....
