POPPING in intake or exhaust? 5.3 heads, headers, cam,tuning with hp...whats this popping sound? Tune was going good then all of a sudden i get on it and its makin a popping sound.. any info on why it would be doing this would be great.. what to change? have really only done idle tuning and throttlecracker to get it to idle and run good enough to drive it.. lol
