JMT Calibration
From B58 Wiki
If you want professional help with the tune on your car, you can contact JMT Calibration. The best email is jeremy@jmtcalibration.com.
We tune modern BMW engines, notably the B58, S58 and S63, can dial in most setups, and are happy to talk about your build in advance if you are unsure about the best setup for your goals or budget. We have been helping builders, self-tuners and professional tuners for a number of years and share a love of the engines that BMW have created.
