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. VF's engineers have full control over boost pressure, waste gate management, ignition timing, and fuel delivery.

VF's 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.

Expertly calibrated and meticulously refined, HEX Tuning’s ECU software for the Mercedes AMG CLS63 is guaranteed to give you MORE of a good thing. More horsepower, more torque, and a more exhilarating driving experience by delivering usable power through improved throttle response and torque management.


With modern automotive technology, gone are the days of “chipping” (or physically modifying the vehicles ECU) but there are still some instances where the ECU must be removed from the vehicle in order to enable flashing capabilities. For today’s popular McLaren applications HEX Tuning will require the vehicle to be present at VF's Anaheim, CA facility, or for your ECU to be mailed in to their offices. Once received the ECU is then professionally opened in order to be put into boot mode so it can then be programmed with our own proprietary performance calibrations.

All ECU’s are processed and turned around within 24-business hours from the time they are received. In most cases HEX Tuning will even cover the cost of return shipping via UPS Next Day Air.
