Straight out of the crate Special Edition Raptor Without any modifications seems to backfire most often between shifts. It has only approximately 6 hrs on it and I absolutely love the power and handling however it is at the dealership right now probably be a few days before they get to it and being fuel injected im lost and cannot find another Raptor owner who has had a similar problem. Would i just be better off buying a controller myself and richening up the top end. But then my warranty would be voided and Id be out a Sh*tty running quad from here on. Anyone with some knowledge on this help me out if you could. Also when i backed out the throttle limiter it seemed to worsen the problem making me think i was just hitting the rev limiter early however it doesn't just do this when at full throttle during deceleration downshifting as well. Thank You for any help.
