Turbo tuning parts > Forge Blow off valves | FMDV18

This valve kit allows the fitment of a fast response blow off valve on the VW Up 1.0 TSI/GTI engine. As the engine does not have a diverter valve fitted as standard, Forge Motorsport have developed a twin piston dump valve that not only gives you an incredibly loud sound when lifting off the throttle but it also increases the throttle response during gear changes by reducing turbo lag, it is designed to help the turbocharger maintain its rotational speed ready for when you accelerate, as well as prolonging the life of your turbo.
