GFBÀTMs Turbo Management System (TMS) More Power - ours holds the boost, can yours?Factory diverter valves are commonly known to leak or fail, especially with age or higher boost levels. A GFB TMS will hold as much boost as you can throw at it, 24/7 - No frequent re-builds or replacement required. Better response through reduced turbo lagThe GFB TMS is designed specifically to minimize lag - tests show that it can return the engine to peak boost up to 30% faster than a factory diverter when shifting gears, whilst delivering up to 40% more transitional boost*. Better Drivability - smoother than stockFactory diverters tend to operate either fully open or fully shut. This can cause annoying surging at freeway speeds, requiring constant throttle corrections to hold a steady speed. The GFB TMS completely eliminates this problem, making the car smoother to drive.
