piston lift pump pressure ?'s

Well I converted my truck to the p pump piston lift pump and installed a autometer ultralite II electric fuel pressure gauge.. it reads 55 psi at idle it draws down to say 50 psi driving it hard.. I rechecked the fittings, and bled the air all out and tried different settings on the needle valve setup to adjust it more.. and still 55 -60 psi.. man thats pretty high... I will have to check it with a mech oil pressure gauge tommarrow..it runs good and has no leaks so far..any ideas...? at least when I swap the p pump it will have a load of fuel pressure its its correct..
thanks,
Deo
