ALL THE PERFORMANCE WITH OR WITHOUT THE NOISE!, GFB’s Mach 2 utilises GFB’s proven TMS Technology to ensure rapid boost recovery on gearshift and optimum throttle response, as well as the ability to withstand boost pressures of 100psi+. Put simply, it can hold more boost than any turbo could produce
