Dotson Tuning & EFI Performance

I’ve worked with EFI since 2016, when the shop was known as EFI Logics. I’m typically at the Bethel shop twice a month for several days at a time, tuning customer cars and working with the team on their builds.

I also provide calibration and race-engineering support for EFI’s race cars and the Subimods GRIDLIFE team.
