disabling pair valve with flash simpley stops the fi code u recieve if pair valve actuator is removed/unplugged. pair valve still operates normally injecting air into exhaust just as before flash. best/simplest solution leave valve plugged and plumbed, block off pair valve hose to airbox to stop air entering exhaust. that's the difference. must be done before any tuning whether dyno, auto tune to get accurate afr. there is residual fuel in exhaust on abrupt decel in any bike, with no oxygen present from pair valve or ex leaks goes unnoticed as in no popping/flames.
