MHD OTS maps for F/G Series BMWs offered through MHD are developed and maintained by PureBoost. With over 20 years of experience in engine calibration and tuning, I ensure each OTS map is continuously refined and adapted for optimal performance across a wide range of hardware and fuel qualities.To further improve these calibrations, I am always looking for motivated test users from around the world.
