More horsepower, more torque, and a more exhilarating driving experience by delivering usable power through improved throttle response and torque management. With additional ft. lbs. of torque through the mid range, acceleration out of your favorite corner and onto the straight is noticeably quicker throughout the rev range.

REQUIRES PROFESSIONAL BENCH FLASHING

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 this application HEX Tuning will require the vehicle to be present at our Anaheim, CA facility, or for your ECU to be mailed in to our 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. VF Engineering will provide complimentary UPS Ground Return Shipping or you can request faster shipping for a cost.

Software tuning provided is designed around the stock vehicle. Any major changes in airflow components such as high flow cats or enlarged throttle body diameters may require custom tuning optimization which VF does not include or provide.
