Saw a video on Youtube from JK Gear & Gadgets on this app called OBD JScan. The app is free, a VIN license is $15 and you need a bluetooth OBD adapter, I paid $25 I believe. Way cheaper than a pro cal. I changed the tire size, compared my speed to another GPS app and It's dead on. Also was able to program my fog lights to stay on with the high beams.

I still need to program the TPMS. I'll let you know how it turns out.

Anyone looking to get into the computer and change basic stuff, definitely try this out. It can do a lot more than just that too. Check it out. You won't be sorry!
