I have an'05 f350 and I am wanting to find out if it is true, if you run a programmer on your truck does it void the factory warranty? Then what anyone's recommendation would be for a programmer. I am currently running a predator chip in it now.
From everything I see the dealer has to prove your programmer was the cause. Did it cause the overheat for example. I have a bunch of friends here that use the Superchip with great luck. You just want to make sure before you go to the dealer with a complaint you take the chip out and remove the battery cables for a bit to clear the computer. To get better info on this subject you should visit the forum that specializes on you engine, year, or just the Super Duty forum.
