F3x 335 TUNE
This is our tried and tested tune for an F3x 3-series with an N55. These tunes were designed on a Dynojet dyno and tested in the real world! A Windows computer is required to utilize the RK-Tunes flash software. For an additional charge, we can include a Windows operating tablet and OBD2 to USB flash cable that can be used in place of a Windows operating computer.
