I should have investigated this further before buying a Burger JB4 N63tu tuner. I did not realise my 2016 750i was speed limited to just over 130mph. I never installed the Burger tuner due to other priorities so now I am looking for another answer from ECU flashers. I am not looking for anything that will compromise the excellent daily driver sophistication of the great N63 motor. This car gets nearly 28.5 MPG on the highway using the cruise. What I do want is the speed limiter removed and more full throttle performance without reliability problems. Any suggestions from those with experience??
