Hey guys, first post. I bought my M109 in the summer. Has a Cobra PWRPRO Fi2000 (non adjustable), Cobra swept exhaust (no baffles) and stock intake. It is running rich and its backfiring is progressively getting worse. Thinking about removing the programmer and changing the intakes. Any insight would be appreciated.

Welcome to the forum! Cheers..! 🍻
I would double check if the PowrPro is wired cleanly and properly,
they tend to have a finicky ground wire, so check and clean all
the connections and look for crimped wires etc...
