Factory sensor voltage to value charts?

I guess I should have specified the actual 5.7 Hemi sensors for a 2006 vintage engine, not necessarily the old school ones, though maybe they aren't all that different. I tried the tee thing with what I have, but I don't necessarily have a good resolution gauge to use as a reference for what the values really are. I hooked my air compressor up for the oil pressure and used the regulator on the compressor to try to set a fixed pressure, but it's a harbor freight compressor with a gauge that reads in 10 psi increments, so hard to say how accurate it might actually be. For the MAP sensor I used a mityvac style hand pump with a generic gauge I got many years back for carb work, but working between vacuum and absolute pressure with unit changes in-between kept messing things up.
