Xr6 boost Member 8 Member For: 14y 3m 17d Gender: Male Posted 29/09/12 11:43 AM Posted 29/09/12 11:43 AM When boosting it more then 4000rpm my car back fires and power cuts in and out. when I look at the air/fuel gauge when putting my foot down it goes straight to lean. Recently had car tuned but since have changed dump pipe could this be the problem??
