What kind of spring did you use? I recently installed a Sonnax boost valve (777917-500), and I was not pleased with the pressures I got.

Not the Line Pressure Regulator Main Spring.
The TransGo Line Pressure Regulator Main Spring has been okay...
Other Guys here purchase Springs from "Lee Spring" and "Grainger".
