BMW M5 F90 comp corrective tune

Not too many people doing the Bosch MG1 ECUs like this one on a 69 plate BMW M5 comp.

 
Most people going through the OBD, this will change the flashcounter, also leave a trace.
We will always where possible tune the ECU directly which will not show on the flash counter and not leave any traces!
