Trust him. Tial imho advertises over sprung ratings. Plus.. I set my bypass valves up to be light on the seat at idle. This helps improve response. You will have boost equalization on each side of the bypass valve and 8psi differential(the spring) should be sufficient to hold any valve shut at wide open. The trick is to have a valve to open correct under part throttle conditions. If you're hunting that it's another story. It's something I've learned how to do over the years, and no hijack intended ( the greddy fv was 10x the tial in drivable).

My old bov [ HKS ssqv ] was good during part throttle operation but after a WOT or during sudden throttle lift off it wont open .
