Exhaust Popping on cold start-up I have the D-1SC.Every since it was installed it pop's & shoots flames on cold start-up. It only does this 3-4 times then it goes away and idle's fine. Anyone have an answer what might be causing this?

i have the popping problem on my stock trans am ws6; guess its just cold and its running rich so it doesn't quite burn all the fuel, so it re-ignites in the exhaust. the whole shootin flames part i don't know about, prolly runnin a LOT rich from a tune. I could be wrong tho.

If you jave flames coming from your exaust > you are running way to rich at cold start. I'm no expert on tuning > but I'm sure you can fix that some how. What have you changed in your fuel system? Have you changed your plugs? You might be running with to hot of a plug too. I get something like a NGK TR6 or TR5. Good luck!

If you have a chance, take you car to a dealership and have them check your a/f mixture with a tech 2 > or if you have a friend with EFI live or autotap. Something is not right! Poping is pretty normal, flames > bad.

Yeah I hate when that happens. As said before, check your a/f ratio and tune your after-idle a/f ratio to whatever it is before warm up. That'll get rid of that stupid "quiet" exhaust and keep u popping all day.
Oh.... wait a sec.... u mean that the popping/ banging/ flame shooting is the problem?....
