I would think long and hard before you delete it. I bought a 2014 F350 for my daughter that is deleted. It has been a total PITA. I wanted a second key as it only came with one. Can't get a key programmed as everyone is afraid if they try it it may cause the computer to revert back to it's stock flash and then I'm SOL since all the stuff has been removed. Had a few other electric glitches with TPMS, Oil change indicator, etc and same story. Can't do anything for fear the truck won't ever run again. I'll never own another truck like this, just not worth it. Don't get me wrong, I'm not suggesting I'm a fan of all the crap they put on the trucks now but if you go changing it better know what you are in for.
