CA Dealers
California dealers are the worst, I've seen it a couple times.
I personally have never had a problem, but its a new 75k truck so i want to be very careful.
At the dealer level most will not be able to tell if the calibration has ever been changed. Your larger dealers and the engineers in Detroit can. We deal with many dealers directly all over the country and not one has ever had an issue with a tuner or other aftermarket component being on a vehicle. Personally I have never see a Ford dealer void the warranty just because.
