Hey guys I bought my 08 Jk used and I'm trying to figure out if it has been tuned or not? I'm leaning towards yes because my rims have no pressure sensor and there is no TPMS light on the dash.i don't know if someone just used a flashcal or a flashpaq? Any way to tell? And I want to purchase a flashpaq in the very near future but I don't even know if you can flash an already flashed ecm? Is there a way to just reset the ecm and start from scratch? I know I asked a bunch of questions sorry! Thanks guys!
