GFB Diverter Valve (BKI only)
Direct Replacement For Factory-Fitted Solenoid-Type Diverter Valve
The TMS range from GFB is designed specifically for the purpose of turbo lag reduction, and improving throttle response. Tests show TMS features can return engine to peak boost up to 30% faster than a factory diverter valve when shifting gears.
Unlike other aftermarket Bosch replacement valves on the market, the DV+ will hold as much boost as you can throw at it WITHOUT the need to adjust the spring pre-load or purchase different springs. This is because the pressure-balancing design of the DV+ means that under wide open throttle conditions there is equal boost pressure on both sides of the piston, so it will stay shut under boost REGARDLESS of the spring setting or the boost pressure.
