@Milli thank you very much for responding, i thought i had found all the tuners on the map but it turns out that i had yet to find the U.S. Muscle tuner.
i have since found it and have been tuning to my hearts content.
@Milli i was wondering why you can't tune any of the cars from Dodge Chevy or Ford in this mod.
I've seen what looks like a Dodge Demon and an modified Raptor but when i go to the U.S. tuner i can't tune any of those cars.
