The boost gauge shows how much boost the turbo(s) is making. It is tapped into the intake manifold.
The oil pressure gauge shows how much oil pressure the engine has. Its sensor is underneath the oil filter, threaded into the end housing.
These gauges have NOTHING in common. Oil pressure and Boost pressure are quite different. Dont trust the stock gauge for an accurate reading on boost. Actually, dont trust ANY STOCK GAUGES FOR SHIT!!!
And if this is on a FD, You simply need an aftermarket boost gauge. I believe if your stock, the boost pattern should be 10-8-10.
Sold...looking for something 3-5 years newer
