New TMS Turbo Management System: Don't throw your BOOST away but INCREASE IT BY up to 40%. GFB's Turbo Management System (TMS) parts offer multiple performance benefits over factory diverter valves. We looked at the concept named ‘blowoff valve’ and took this to a whole new level!

The benefits:
• MORE POWER - Ours Holds Boost, Can Yours? Factory diverter/blowoff 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 lag - The 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, while delivering up to 40% more transitional boost.
• BETTER DRIVEABILITY - Smoother than stock. Factory diverters tend to operate fully open or fully shut. This can cause annoying surging at freeway speeds, requiring constant throttle corrections to hold steady speed. The GFB TMS completely eliminates this problem, making the car smoother to drive.

What makes the MACH 1 a better Blowoff Valve?
• Advanced TMS benefits
• Spring pre-load adjustment for max. response
• Venting options: You can decide if the blowoff isn in Full recirculation (silent) or Full Atmosphere (loud!)
