This is our tried and tested tune for the N55 platform. These tunes were designed on a Dynojet dyno and tested in the real world!
We personally recommend using MHD for all tuning(requires purchase of MHD adapter and flasher license), but is not required if you are only using our OTS tune. Only required if you are seeking custom tuning/datalogging, you must also purchase the MHD monitor license as well.
If you do not want to use MHD, a Windows computer is required to utilize the RK-Tunes flash software. The device must have a ethernet port, or you must have a ENET to USB adapter. Check FAQ section for windows device recommendation.
