RE: backfireing

Are you sure it isn't Lean Pop that you are hearing.... When you roll off the throttle, you hear a pop or light crack out of the exhaust...

Whoever did the Dyno Tuning failed to properly tune it.... That is not normal with a properly tuned PC...

Dealer is BS'ing you.... They did a sloppy job and got you to bite... Did it do it before???

Absolute Truth. With a SERT or Power Commander and a good dyno tune you eliminate the back firing and popping. Like mentioned above, your dealer is B.S. ing you. Not everyone is competent running a dyno. Check around or take it back and let them know you are not happy.
