Whats the oil pressure guage got to do with a TIP paddy?
You sure you don't mean the boost guage?
10psi of oil pressure is bad news!
you might have got an oil pressure problem there. firstly what guage have you fitted?
oil pressure wise,
from cold even on idle you should have 40+ but not going above 80 when revved.
when hot you should have 20psi minimum..... hold a few revs say 2000 you should have atleast 40, then it should go up incrementally with the revs.
