its not the e30 mix causing misfires. ive run e50 on the BMS stuff for the past 8 months with misfires only happening above 21psi. seems the leaner the AFR the less the car misfires. i have a few bms flashes and the leanest 13.0 afr targets allows most boost. now im trying ptf tunes and its misfiring at 19-20psi on 12.xx afrs. ive tried new hpfp, plugs, coils etc etc. nothing changes the misfires. how much boost are you hitting?
