I dont want to seem like a dumbass but i do need to ask, Story goes I just got my vlt back from tuner it WAS a basic setup before hand but now a rebuilt motor 3540 and so on installed pushing 380rwhp through a manual, my question is when I have the revs almost on limiter if not touching the limiter every so often theres a really loud bang and somtimes a flame from my exhaust now I am thinking its just backfire from so much fuel and so on its just that I want to know if ita common to do this or if somthing isnt right? I talked to tuner who is basically 600kms away he says it is probly just backfire but it is quite loud... il try link a video later cheers sorry if im making ct tool of the week hahaha

Sounds like you are hitting the limiter thats y its is backfiring and poping

Sounds like a hard cut limiter so everything shuts of quick

Ok I wasnt sure as I do get ur basic limiter noise followed by the odd loud bang
