just installed my Jb4 and Denso plugs But no boost at all. Everything else seems fine. What gives? (I had this done at a well known speed shop in Brooklyn). Thought maybe I need to do something or I will go back. There was a pop (like a backfire) so wonder if that has anything to do with the issue. (I love the exhaust sound now)

Ah... adding JB4 and plugs shouldn't have in any way affected the exhaust sound...
