The Forge Valve Large Spring tuning Kit is designed to precisely tune your diverter or blow-off valve for optimum performance. If you notice that the valve is blowing off more than necessary or if you are losing boost pressure, this is usually an indication that a stiffer spring is required. These springs are available in various strengths and are designed to suit different turbo pressure ranges. Compatible with the following dump valves: FMDV004, FMDVRMA, FMDVV4010, FMDVSUB01, FMDVMAZ301, FMDV008, FMDVC200R, FMDV5R, FMDVRMR, FMFOCSTDV, FMDVC200A, FMDVFRS2, FMDVMAZ3.
