Product Description
We recommend servicing your valve every 3 years, or 20,000 miles, whichever comes sooner
This has been designed by Forge Motorsport as a direct replacement for the compressor bypass valve (CBV) that bolts directly to the turbo . It replaces the OEM diaphragm type valve with a piston design that allows for tuning with interchangable springs. For those running higher boost pressures after software tuning this really is a must to ensure that you do not lose boost through the valve. 
In The Box:
1 x FMDVRMR Valve
1 x Uprated Yellow Spring
1 x Uprated Blue Spring
3 x M6 x 16 Socket Cap Bolts
1 x Forge Sticker
This product comes assembled with a green spring but is supplied with an additional uprated yellow spring. If your car is a Renault Megane RS250, 265, or 275, then this spring should be fitted instead of the stock green spring. If you wish to further tune this product to fit the needs of your engine, please see the spring tuning kit below.
