So has PPEI done quite a bit of testing for their X3 tunes?
Is it open source, meaning, can you go in and modify the tune if you want to? Or is it locked?They have. Kyle Chaney races and uses their tuning, and the owner also races himself. They officially released tuning for the x3 back in May of 2020 which I'm sure they did in house testing for quite some time. as of now they are tuning 2017-2020 Turbo R models, and can tune the 120hp Turbo cars that are upgrading to Turbo R specs. They also can tune the 2020 Turbo RR models as well from what I understand.
