How to remove a custom tune

The previous owner of my truck has a 50hp custom tune on the truck. How do I remove this tune? I'd like it to be stock until I get my new chip especially after installing my new o rings and glow plugs.

Was it chipped or reprogramed? If it was chipped just pull it.

There's a Fuego tuner that came with it made for custom tunes I believe. Do these have chips I thought it just went straight into the ob2 port? Where would it be located if it does have a chip for it?
