Eliminating DFCO
Hey guys,

I was told that eliminating the DFCO (decceleration fuel cut-off) would eliminate the afterfire from the exhaust. Anybody know how i can do this? Id appreciate the help. Thanks!

how would it eliminate the popping sounds from the exhaust? I thought DFCO cuts fuel off going to the engine completely when the throttles not depressed at XRPM.
