I had my car tuned at my local speed shop and they used HP Tuners. I want to purchase the program myself and do my own changes. now my question is if I purchase HP Tuners, can i save my current MAP theway it is and go back to it at anytime? or because it wasnt from my device it work at all?
I would like to save it, and change my shift points and stuff like that.
Help please!
