Where have you plumbed the boost gauge vac pipe to?
The oil pressure one sounds like the sensor wiring is incorrect.

Put the boost gauge in the engine bay and just plug a hose into it from the inlet manifold. There should be a couple of spare nipples so just use any. See what reading you get, if its high you know the gauge is dud.

Oil pressure, which type of sender is it ?? Is it the large round one with two terminals, if so make sure you've got the wires on the correct terminals and that the - terminal goes to a good earth.
Sounds to me like you've got the wires mixed up or a bad earth
