I'm wondering if this high idle issue this vehicle is having is due to a na fuel controller with a tt ecu since I swapped a na ecu and the idle lowered to a reasonable amount (900~). Of course I also want to make sure the vehicle runs properly as well with a tt engine. I have a friend that can do all of the programming, although he said a tt ecu + na fpc wouldn't make idle higher, which makes sense, but from the evidence it doesn't seem so.
