The problem with stating that Ford can tell you had "a tune installed" is misleading. Ford cannot tell WHAT tune you had if you return it to stock before they examine the problem. They CAN tell that the ECU was flashed - I believe it shows engine start counts. However, what is "a tune"? I have my truck that has "programming changes" for a 170F thermostat that I installed. It just commands the fans to turn on earlier at a lower temperature because I tow a boat here in Florida in the Summer heat. It also has the START/STOP switch always turned OFF so I dont have to push that ridiculous console button every time I get into it. So, what does "a tune" mean exactly? My point is, Ford cannot tell what type of tune or reprogramming was installed, only that the ECU Start count is very low (because something was erased and a stock program was uploaded). If my transmission is toasted, and they see the START counts on the ECU are very few, they can assume that it appears I reprogrammed the ECU. That IS a true statement. But, if the transmission lunches and it was NOT related to my tune (which they don't really know what my tune was), then they have to repair the truck. All I'm saying is they would have to have documented evidence proving that you modified the truck as an Owner, and most importantly that your mod caused the issue. And proving that is pretty hard to do when Ford doesn't have your "tune" to see what it actual did/does. On this Forum, there are a number of Raptor owners that have had issues with their stock trucks. It is important to understand that if and when you ever experience an issue, that you can poll the rest of us to see if we experienced that same problem. If we did, it's really hard for Ford to state your problem is unique and wiggle out of paying for the issue as long as the truck is under warranty.
