IIRC, you have an 870.
The turbo efficiency of them is around 1.8:1, so it should be intake pressure times about 1.8.
A turbo pushing 38psi max will be in the ~68psi exhaust manifold range.

Are those real world numbers or what Holset says? Maybe in some spare time(lmao) I should hook up a gauge and see.
