That is exactly the same BOV that I have. Why do you think you have compressor surge? What do you mean by lower tolerance? Have you tested the BOV to see if it is functioning correctly?
Sometimes the diaphram in the BOV leaks. This will keep the BOV from opening properly which could cause compressor surge. There is an adjustment screw on the top of the BOV. The lock nut on mine vibrated off causing a vacuum leak and partial BOV failure. If you adjust it you want to adjust the butterfly valve in the BOV so that it opens completely.
Edit: Jonny, I checked your garage. There's nothing there. I can't really remember what you're running. Weren't you running 14 psi once? I don't remember, maybe that was someone else. It helps us give better advice if you keep your garage updated.
