I've only got i/h/e but am planning on a cam (zex stage 1 for torque purposes), cam gear, throttle body. can uberdata work on an auto tranny? (i'm keepin it auto) if so, will i see any major gains or just minimal since its all motor. i was considering a vafc but i've heard bad things bout it that its not reliable and not worth the money. with uberdata, i know i'd need the obd2 - obd1 converter harness and a p28 ecu that is chipped. then what? just get it tuned with uberdata? thanks
