Like other said; handheld thing talking to the ECM, etc.So what’s involved with the tune for the engine?
change thermostat and spark plugs? Is that it?as far as the engine goes?
does the heater still heat good in the winter?
I am pretty sure their tune will do what the LMS tuner does - you will get to see EVERY warning screen that Ford programs in as it rewrites stuff. It might make some panic to see that amount of crazy.
The funniest warning was the one that said to read the owner's manual. Not 100% sure what triggers that one unless the truck senses you are an idiot and need to read said book.
