I haven't found a way to stop mine yet. The only thing i have noticed is that if i don't let the car hold it self back, going down a hill or something, then it doesn't do it as bad. Mine only does it when the throttle is touched again after letting the car coast in gear for a couple secs.

get some sort of engine management. Rallitek PerfectPower6 is recommended. Otherwise, have a resonator welded in and that will at least muffle it some.

i used to have serious back fire problem, but after i changed to WRX axleback the problem is just gone. now i missed the back fires now~
*ps, exhaust mod = brullen header/cat, apex'i N1 midpipe, WRX axleback*

so if you want to get rid of the backfire, put stock muffler on~

good luck. Dealerships don't really have that capability. It runs rich because that is "safe". There may be a reflash available for you through I-speed or you can tune fuel trim/timing with the PP6

PS: I said resonator first!!!!!

Dealerships do have that ability, but good luck getting them to do it for you!
there was a recall a while back where people were getting there ecu's reflashed. I know it was a certain run in one of the model years before the new ages so you may be in luck if you do some research.

like $80 installed. technically it does a little....but its really not that big of a deal. its basically another muffler. and how much power would someone actually gain by taking off a muffler...not anything noticeable. if anything it would be a placebo affect of: wow my car is loud and soooo much faster. /rant
