Do you have an aftermarket boost gauge? If so what is it doing and how much boost are you running. Probably boost blowing out a ic pipe. Could be a bad bov as well. If you don't have a gauge or data logger all you can hope to get is educated guesses.
Not using sentences makes it hard to understand what you are trying to say and some may simply not bother figuring it out.
Yeah I don't have a gauge I was trying to figure out if it was boost solenoid so I went to wastgate boost. Was trying to find out if it was spark blow out or fuel cut also has a popping when u let off throttle it pops and at idle it pops I can post a video.
