If its a chip, you look at the pcm located on these trucks on the firewall, drivers side, you kind of have to get to it by unbolting the fender. There is a 10mm bolt holding in the wiring harness. Then you slide it out and look and see if there is a TW (or other) chip plugged in.

If its a tuner, then you need to plug it into a computer to check

take off the 3 bolts of the ebrake and under there is the pcm and there is a hole and on mine it had a plastic cover but some dont.

Its easiest to take off the 3 bolts of the e brake than to slide out the PCM underhood.
