What is your idle set at? My 350 will push about 22-28 psi at idle, 50 psi at cruise and 60 at wot. If your idle is set really low it could be giving you your low numbers.

I have my idle set at about 850 rpm's in park and that puts me at about 650 rpm's in gear.

Unless you have a leak in your gauge line, these mechanical gauges are pretty close to right. Also, I have never been one of those guys that has been a big believer in synthetic oils except in my diesel trucks. But odd as it is I gained about 5-8 psi at idle when I switched to a good syn...who knows?
