Hey I just ordered some headers, catback, intake and a new therm. When I called the shop that did the work on my GTO they told me they can't do a custom tune a dodge. Now I need to know what to do. Find a shop to do a custom tune or buy a predator and do it myself. For the record i have never done that before. How hard is it to figure out? I am very tech savy but have never even seen a predator before. Any advice?
