When I am pushing the car hard and I shift quickly sometimes it will make a loud popping noise is this backfire in the intake? If it is backfire in the intake how do I fix it? If not what is causing this sound and how do I fix it?

Are you pulling any codes? It could be a misfire.

Could be raw fuel exploding in the exhaust, I know a guy with a supercharged 306 that when he lets off the gas it pops .

Did it always have a CEL even after the MILS?

I have a friend that has a 94 cobra and we put a bbk fenderwell mounted cold air intake and his did the same thing. It only did it after we installed the cold air intake.

I can just tell you what happened to me and my friend. Did you have the problem before the densecharger?

Yea it was happening before the densecharger but it seems like it got worse after I installed the densecharger like it started doing it more. The check engine light has been weird. At first when I put on the O/R H-pipe and the MIL's it wasent on then 2 weeks later it came back on, and it was reading that it was an o2 sensor so I replaced that o2 sensor and then the CEL stayed off for anohter 2 weeks or so then came back on.
