I bought a mellings 60psi pump and did the mods with the smaller checkball and the washer shim behind the spring. I also added the 1/4" thick bottom plate from NightMare performance.

My pump now shows 80 psi almost all the time now. I put in a really thin oil and got it down to 70psi hot. No idea why its 20 psi higher. I guess I will just live with it, betten then too low.
