We’re proud to announce another industry first for the Volkswagen and Audi tuning market from Forge Motorsport!

Many owners of any VAG vehicle equipped with the all new 2.0T FSI engine, have unfortunately discovered, that the OEM electronically controlled bypass valves, which bolts directly to the compressor cover of the turbocharger, have their limitations. If you are running increased boost pressures, after a software remap (chip), or the OEM valve is being subjected to high temperatures, the lifespan of the unit is significantly reduced.

We have seen diaphragms split

and also the diaphragm / piston break away from the solenoid shaft

We now have the world’s first fully engineered solution offering both significantly improved reliability as well as valve related boost response. Our valve and installation kit replaces the original unit with a pressure/vacuum operated piston valve that still also retains the desirable OEM ECU control over valve actuation. This product has been thoroughly designed and tested with the expressed intent of offering improved valve response and maintaining ECU control while resulting in absolutely NO fault codes, NO check engine lights, and no adverse effects of any kind. All of the necessary components and detailed instructions are included and everything is designed to make installation as simple as possible.
