Cool. I wouldn't be at all concerned about the backfiring; in and of itself, it causes no damage and could just as easily be attributed to a phenomenon known as reversion ("suck-back"). I would, however, monitor the plugs fairly closely for indications of an overly-lean condition, especially if you spend much time in the elevated-speed, constant-throttle mode. Once you get your fuel controller installed, your be able to fatten-up the mixture a tad and sleep a little easier.no fuel controller, dealer said it really wasn't neccessary, just a little backfiring but i like it!! I paid 240 bucks for the whole set-up from a guy on here who had swepts installed on his fury. i want the spike intake and then i will probably go with fi2000 controller i think its called and put it thru the dyno. Thanks for listening though, I was beginning to think no one liked me on here....
Hey yeah! Thanks for posting that!
