How is this "ECU Flash" any different from BMS JB4, ECU Tunning, and Dinan?
They all fairly do the same thing by raising PSI boost to produce more horsepower.
Unless there is a full actual ECU Tune I don't justify paying anything more than what JB4 offers.
I am very content with my 667 rwhp 2014 ///M6 Competition Package with RPI downpipes, custom race exhaust, BMS JB4, and VP Fuel MS109 octane.
Till I see another new ///M Car beat me at Shift S3ctor or see videos of taking on an Mclaren MP4-12C like I have by 3-4 cars, I stand strong with my setup.
