Bought 2019 Raptor last month--was told it had a tune. Got the Ford Pass app and see that i have a couple things to be done--21B10 and 21nN08. Take the truck to Ford and am told they can't get around the tune on the truck tp perform the update. No record of the tune brand or any specs whatsoever as truck was a trade in. Anybody know a way around this as Ford is telling me I need to get th updates and any further updates in the future. Thanks
