I'd like to make a few changes to my 2018 Ram 1500. I need to recalibrate the speedo, change the tire pressure setting, remove the speed limiter (105 mph!!), and something else I can't recall at the moment. I don't have much interest in additional tunes, but would fiddle with it if I got the functionality as part of the deal.
I think I've heard of software you run on a laptop, and also dedicated programmers. That is the extent of my knowledge.
Can you guys recommend hardware or software to address my wants?
