VF-Engineering and Hex Tuning have developed an impressive software package for the M3/M4 (F82 chassis) that leave the BMW’s twin-turbo engine with sizable increases in both hp and torque. Programmed through the OBD2 port, this seamless upgrade remains un-intrusive, and fully reversible. GMP Performance is proud to be a dealer for these powerful flashes and having met with the experts of HEX here at our shop at Charlotte, we're enthusiastic about getting some of these tunes out in the world!
