How can I tell if my truck was tuned?

I just bought a 2008 F350 CC FX4 with 28000 miles on it. After taking a closer look at the truck, it looks like the previous owner put a leveling kit on it (which I would like to take off), and I have noticed that my dash right next to the steering wheel on the left lower side is kind of messed up. I did not think anything of it at the time, actually I could not determine why the dash was screwed up (it looks like it got either melted or chemically burned in some way). I thought it may have been from a cigarette, but the truck has no other signs of being a smokers truck. Could this be from adhesive that would have held a tuner? I really would hate to go in for warranty and find out I am throwing the code for a not stock tune and have my warranty voided.

I would have a trusted non factory guy scan it and tell you. also find another truck like ur's and drive it to feel the diff.

The truck definitely feels like the other 6.4s that I drove. It does not feel as though it is currently tuned. How do I find "a trusted non factory guy scan it and tell you?" Anyone got any suggestions in southeast Michigan?
