As stated this is usually from rich tunes, it's easy to get to flair up because a quick WOT blip will cause it to go CRAZY rich when the throttle closes. Once the hot fuel gets somewhere with oxygen it burns.



I suppose with the direct injector you would have the option of adding fuel while the exhaust gas is getting pushed out. You might even be able make it have constant flames if you really wanted. I don't know if ecutek or unichip would allow a tuner to do that.



In theory it might even cool the combustion chamber enough to allow a little more power. If you can it would even reduce the amount of rice that comes out of the exhaust with the flames.
