exaust back firing on decel??? has anybody experienced big time back firing on decel at almost every rpm range above 3000 rpm. It's so bad that my buddy following me the other night saw flames popping out of the muffler. FYI i have LT headers no cars and a dynomax muffler that dumps before the axle, any help is appreciated

Do you know if your fuel over-run on deceleration has been turned off maybe when car was last tuned.
It usually is associated with the tune.
I had my car tuned & it drove me crazy with the constant back firing, took it elsewhere to get it fixed & now it's a pleasure to drive.
