HEX TUNING FOR BMW | M3 & M4

How is HEX Tuning different from other products?

HEX Tuning is designed as a "full flash" tune, meaning the entire data area of the ECU is reprogrammed to create and sustain more power.  "With great power comes great responsibility", safety MAPS are programmed into the tune to pull power if an issue occurs. Our engineers have control the boost,  waste gate, ignition timing, and fuel delivery.

Our tunes are developed on "pump gas" 91 octane. Using 93 or 100 octane would only enhance the driving experience of your vehicle. Higher grade fuel allows for accurate time and ignition, cooler engine,  and better performance.
