The Forge Blow Off/Dump/Diverter Valve Internals Spring Tuning Kit allows you to match your Forge valve's internal spring pressure to your engine's boost output. It includes four colour-coded springs, each suited to a specific pressure range for more precise and effective valve control.Explore the key features of this tuning kit:Colour-Coded Spring Selection: The kit includes green (5-15 PSI), yellow (15-23 PSI), blue (23-30 PSI), and red (30+ PSI) springs, each offering a defined boost range so you can choose the most suitable spring to maintain consistent valve response across different operating pressures.Defined Boost Pressure Ratings: Each spring is specifically calibrated to operate within a set PSI window, helping you achieve the correct balance between valve preload and boost level for accurate function during throttle changes.Designed for Forge Valves: The springs are made exclusively for use with Forge blow-off, dump, and diverter valves, ensuring direct fitment and reliable compatibility without the need for modification.This kit provides the flexibility to reconfigure your valve setup when engine changes have affected boost pressure, such as after installing a new turbo, remapping the ECU, or upgrading induction components. Matching spring pressure to your current setup helps maintain accurate valve operation, preventing performance issues caused by incorrect preload. It's a smart addition to your engine bay if your build has moved beyond factory boost levels for higher-stage tuning and you want to keep your Forge valve working as it should.Please note: This spring kit is only compatible with Forge Motorsport valves. The red spring must not be used with the Forge DV007 or DVR diaphragm valves. Installing a stronger spring will not increase boost pressure unless the boost control system is adjusted accordingly.
