More POWER for your ///M. HEX Tuning by VF Engineering delivers more than just power - It’s engineered to provide consistent and reliable performance on the street or at the track in a way that inspires confidence ever time you press the pedal. The HEX Tuning software upgrade for the S55 3.0L turbocharged engine found in the F8X M3 & M4 is a proper ECU recalibration that works in conjunction with the ECU’s self diagnostic and safety features, including but not limited to, advanced OEM knock detection. This approach not only allows for more consistent and reliable power than “piggyback” tunes, it also ensures that the ECU functions as originally intended while providing noticeably increased horsepower and torque delivery even with different fuel qualities, under a wide range of driving conditions, and in various climates around the world.   Audi Downloads BMW Downloads
