I'd be curious as to what parameters of the tune have been changed for the NMRA sealed engine. The obvious one is the rev limiter, but what else in the tune is changed? Has timing been adjusted...has anything in the tune been changed to accommodate the VP C10 fuel? And what is the baseline tune modeled after...a stock 5.0L Mustang tune? If the tune is sealed and nobody can change it, then releasing what those changes are should be no issue right?
