I am getting ready to install my new Oil Pump. I have hand portes the internals and the inlet as well. I have read that some of the aftermarket suppliers shim the relief springs to acheive more pressure. Does anyone know what thickness of shim that SLP or Texas Speed uses?

 

I shimmed mine like I seen on a youtube vid, but my pressure is thru the roof, so i would like to take it out. I have 60 @ idle, over a 100 down track. i wish i left it out.
