Glanza_cl Posted February 12, 2009 Share Posted February 12, 2009 then it shouldn't really pop flames, the only reason i know of it fuel cut that's when the car goes over it's stock boost level around 0.85and for safety reasons fuel cuts happens, this will result in a big jerk then sometimes a backfire or flames as there is unburnt fuel in the exhaust.if you don't already get a boost gauge, then see what you are boosting at before it happens and report back.
