is anyone running map ecu? my car was on the dyno and under light load everything is fine, smash the throttle and it pulls extremely lean then very rich. backfires and throws dtc 31 and 34. MAF and turbo pressure sensor. then goes away. has anyone had these problems and or found a fix? any direction would be a help

From what I can understand. You "smashing the throttle" is surging the pressure in the manifold, sudden rush of air would lean out the mixture before the ecu can compensate, when it does it over compensates.
Its acceleration throttle, or tip in or some stupid name like that, you can fix this with an aftermarket ecu.
