FPR Shim Question

FPR Shim Question
I shimmed my FPR last night using a BB, and it made quite a difference in the way the truck runs - more throttle response and smoother idle. I measured the pressure using just a regular tire gauge, and it bumped it from ~50 psi to ~70 psi at idle, according to my gauge. I've read that 70 psi is optimum, so I'm happy. My question is this: How accurate is my tire gauge measurement? Has anyone checked a tire gauge measurement against a measurement with a gauge that's designed to work with liquids? Guess I'm a little paranoid that my measurement could be off - I don't want to over-stress the fuel pump.

I put together a clip-on tire chuck,1/4 inch needle valve and a liquid filled gauge to check mine. It works real good. The needle valve can control the spikes and the liquid filled helps some also. Clip it on the tire chuck on the scherader valve and start the truck. I never could get a consistent reading with a tire gauge.
I'm lucky enough to work in the oil/gas business and have access to such stuff!
