oil pressure

[dummi]

can we run electric oil pressure guages or plum in a mechanical one? i'm thinking of one as oil keeps the turbos alive it would be a priority to me, that and boost,, what oil pressure should be normal

any other guages worth having like air fuel, would narrow band be any good at alerting to an actual fault for furth examination or is its range too short? i know they would be pointless for tuning, but as an alert to something not right?

EGT is said to be a good tuning mod, but i wouldn't be tuning the car on the fly myself like that

be nice to hear from people with these guages on their worth

cheers
