Backfiring

[RioRedCobra]

Sounds like a damn shotgun when I get on it. Car has a tuner, headers, h-pipe w/o cats, flowmasters w/dumps. Also has IMRC deletes. And EGR delete, and cold-air. Everything else is stock. I know its running rich, but wow. Any way to adjust this so it doesn't happen anymore? Is it my tune?

Just bought this car not too long ago, and don't know a whole lot about it yet, but due to the weather really haven't had a chance to drive it until this weekend..

Thats a tough one. Could be faulty sensor or the tune. Try unplugging a sensor and drive to check results.

If it has a tune, it's probably the tune.

That's what I figure. Guy before me was spraying, and the tune is set up for that. Think it's dumping fuel...

double ck the plug wires are connected to the correct plug. (firing order)

My 01 was doing this after getting on it hard then downshifting. Wideband ratio would read all the way down to 11.9 sometimes. I was told it was just a cobra being a cobra. Nah. I'm pretty sure my timing chains were stretched or something weird.

If if the tune is set for spray then that's more than likely the issue. Get it dyno-tuned.
