I have a 2015 mustang GT with a Paxton, 6r80 and a 3C stall. I am currently using one biggest ford tuners out there and I am thinking about buying the HP tuner software and running the car myself. I know this will be risky and difficult but I have a few questions.
1. Are there and base tunes out there for cars with my similar modifications that I can use as a starting point
2. What is the most difficult aspect of self tuning?
3, Are there any tuners out there that will help you build a base tune for a fee?
