This is my 2nd tune through Ambot, and it’s been worth every penny. Be open with him and he’ll help you out. Ran into an issue with my car having a air leak(Ambot noticed it through logs), took a bit to find it and fix it, but just let him know my status and process, and he was fine with giving me time to get things worked out before going through with the tune. Once I fixed the leak, the tuning process itself took about a week.
Car feels great
