Hey Guys
I have just done a timing kit on my r34 gtt. everything is timed properly and every thing is back to the way it was before I started the only thing that id different if the BOV which is a turbosmart kompact duel port.
The car is idling rough and at like 1k-1.4k and backfiring after being reved a bit.
It did backfire every so often before all this but could this be caused from the BOV?
