RKTunes PERFORMANCE TUNE FOR N63 - TU & NON-TU - 550I M550I 650I 750I M850I X50I

This is our tried and tested tune for the N63 platform. These tunes were designed on a Dynojet dyno and tested in the real world!

2010-2013 MODEL YEAR CARS CAN ONLY BE FLASHED ON THE BENCH. YOU NEED TO SEND YOUR ECU TO US TO BE TUNED. Once you place the order, you'll get an email with a form to fill out for shipping.​​​

PLEASE NOTE: 2021+ MODEL YEAR CARS REQUIRE AN ECU BENCH UNLOCK BEFORE TUNING IS POSSIBLE. 

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.
