Car shooting Flames??

[tom1995tsi]

Well, I was racing my friend today and he was behind me and when we started to slow down he said there was a fire ball that shot out of my exhaust. Iv heard that from other people too. But I have no idea whats causing it or if it is bad. The car sometimes makes a weird sound like the exhaust is shaking a bit. I have a feeling that is when it shoots the fire ball. I have a walbro 255 w/o a fpr. (Dont Flame) Maybe that could be it? Odviously it is not running lean since there is fuel to burn.

There was a thread about htis just maybe two days ago, its cause you are runnign way rich with that 255 and after a hard run the manifold/turbo/o2 housing is so hto that it ignites the unburnt fuel in your exhaust causing you to shoot flames. I am not going to flame for the 255 without fpr but I am gong to tell you to get one so do it, trust me your car will run way better.

besides gas milleage and performance no, it will make it a pain in the ass to tune however so it might hurt your patience but nothing else.

It's a whole lot easier to tune WITH a proper FPR, than without one that can handle the pump.
