+1 for it being a flamethrower kit! lol jp jp rich tune all day long, oh and for it doing it on every shift, it might be so rich that it does and if not dont you think they would have taken out the parts of the vid that were wasted oh him going without the backfire. the flame comes out on a second jab of the gas after the shift, in turn, it means it fuel, not some kit. no jabbing the gas is not the triggering device for the kit either.
