If your car is shooting fireballs only when you let off of the gas, your decell setting sound off depending how bad it is.
I haven't seen my car backfire myself, but from what I heard when people drive behind me it's pretty bad. Sounds like a 12guage shotgun being let off and exstends for about four feet from the back of my car.
But I don't know how true that is.
Both ways I need to fix that problem before I damage my turbo badly.
