I have stainless power LT, and NPP with fuse pull, dynosteve tuned and when I let off gas it pops so loud it sounds like gunfire. Is this bad on engine?

Eh, hard to say. I have different levels of pops myself, normally ots crackly popping but once in a while i get a gunshot pop, a little more fuel built up bigger bang. He might have you a little rich. It can be tuned out completely but i don't think it will hurt anything. As long as its not backfiring through the intake

Well listen to this in comparison to yours. Likely you are experiencing what we all do with the LS based Camaro. One of the members here had his car tuned for decel pop tune a year or so ago and it's insane. It's a bit too much for me, but to each their own. Compared to most LS3/L99s this is not normal. I imagine that would get old real quick.
