I recently bought a Properfekt recirc valve to replace the Forge dump valve that's currently fitted to my R26 and I have a quick question regarding what spring to use in it. I belive the spring it comes fitted with is suitable for stock to 1.3bar of boost, and the supplied uprated spring is for above 1.3bar of boost. My R26 is running a stage 2 map and I see around 18.5psi/1.275bar of boost in my Torque App. Am I better off using the standard supplied spring, or the uprated supplied spring? Thanks
