Has anyone successfully reprogramed an F92 M8 ECU with a custom tune and dyno tested the actual and not claimed BHP/TRQ gains?
Any recommendation on primary and secondary downpipes that have actually been fitted and tested on a dyno to measure actual and not claimed BHP/TRQ gains?
I'm in Sydney and we are super limited with experienced tuners on these cars that have tuning experience.
