6.4 Programmers ???
I talked to my local Ford dealer today. Asked their take about putting a programmer on my new truck. They (they being my salesman and the co-owner of the dealership) said that just adding a programmer will not void my warranty. But, if a part fails when under warranty, Ford requires the dealer to print the info from the ECM. If they determine that the part failed because of performance mods, then they can refuse warranty for that part. They said the ECM does store all info and shows if a aftermarket programmer was used. They said that there are a few companies that make programmers, that when you upload the original facgtory settings, it removes any traces that an aftermarket programmer was ever used. My salesman thought that Bullydog was one of them. Anybody know anything about this?
