so far i took the boost up to about 8-9 psi. I have noticed that I am gettin some backfire. Its nothing real bad, but enough to make me wonder whats up with it. Do you have to change the spark plug gap because of more fuel/air going into the cylinders or is it just time to get new spark plugs or check the gap on the ones already in the engine?
light backfiring?

i havn't removed anything at all, i put in the boost controller and thats it. And if you mean like a real live cat...haha, very funny. But i don't kno if the backfiring has to do with a spark plug gap or not. On other cars i had that was always the problem when it was backfiring
the reason i asked... if you have a full catless aftermarket exhaust, backfiring is normal because you're not "filtering" the air between the engine at the muffler, so combustion will occur. but im sure a bit of backfiring could occur even w/ cats, but then again, what do i know!lncatch said:

I occasionally get a little backfire with the stock exhaust at stock boost.

backfires are FUN. people freak out when i do it......mine are loud as hell too cause I have no cats. the way our cars run rich, its ony normal to get them every now and again...even with cats. without cats though you can make it anytime you feel like it, all you gotta do is tap a gas pedal a little when you coming out of gear, or even in neutral...and it definately back fires on me when i shift at redline.
wait a minute i have backfires too and i have no cats. and i was wondering if fire actually comes out when i backfire. sometimes i get really hard backfires and i wondered if fire comes out cause i saw this wrx last time with a huge flame commin out on a rainy day.
its not exactly firemikeeeee said:
, but the inside of your exaust lights up...., Dr. Sound was driving behind me one day when i backfired VERY loud on purpose and he said that there was a brief blue flame showing a few inches from the tip....it was dark outside as well... during the day all you see is a little black cloud coming out......BTW he has a magnaflow cat and still backfires like crazy....(yes)
