It seems my HUD and Speedometer do not agree with one another, cruising down the highway at 80 on the HUD, it shows I am doing 83 on the Speedometer - any idea which one is more accurate?

Secondly going Highway Speeds what is the normal oil pressure, mine reads about 55 Psi, is that normal turning around 1800 rpm's?

Thanks in advance.

My hud reads 1 mph low when doing 60. GPS (aftermarket) confirms the spedo is correct.

55 PSI with fully warmed up oil (185) is good at 1800.

My speedo always reads one mph high, as checked by the many radar units around here. If it says 60, I am really going 59, for example.
