| Im not real sure on this but the few tuned LBZs i have ridden in have a horrible shift defuel casusing a hesatation befor the down shift. The added fual of the tuner magnifys the defueling making it more noticeable with the tuner!!!! Also could be turbo lag but that shouldent be programer related?
