3071r on 21 psi external wastegate
740cc injectors stock rail and regulator

Power fc djetro

So I went out the other night for a cruise barly boosting the car noT revving it high for about 20 min, got bored so I got on it a few times and it boosted fine all the way to 21psi but once it hit 21 it started back firing and popping ( didn't feel like fuel cut or misfire) so I thought it just loaded it self up with fuel and after beating on it, it cleared up. Would a fpr fix that or anything else???

just sounds like your cat isnt doing its job if you even have one. if its straight piped, running 21 psi on an sr you can gurantee some POP POP as long as its not running too rich. buy a afr gauge?
