more power at part throttle when spooling around town, and no more surging in boost once the ECU decides to add fuel. hey, maybe it's just my car that stays excessively lean for x seconds in boost unless i give it WOT, i dunno. the moment i give it more than 80% throttle i get .92-.93 for oxygen sensor voltages, forcing the car into open loop. i know my fuel pressure is good enough, if i bring it to 8 psi at part throttle it does the fubar thing, but if i mash it at 8 psi everything's fine. i haven't been able to think of any other solution for this problem.
