very low oil pressure and boost spike

[harojake]

so ive got very low oil pressure and when i get on it it should move but it doesnt looks like around 5 or 6 psi, checked the oil and its all there, also when i have my boost set at any amount (electric or manual boost controler) the boost just goes till it cuts fuel, wtf is goin on? lol (boost controlers both worked on my old turbo before it blew, now is a new ct26)

First: get a oil pressure tester and check to see what your oil pressure really is. If it never goes above 5-6psi, you have bigger problems to deal with! If it is normal, the gauge/wiring/sender circuit needs checking.

Next- remove the boost controller from the turbo and run the hose from the turbo housing to the wastegate directly. If it still spikes, your wastegate has an issue, but if it gets better you boost controller has an issue. It might be malfunctioning or it might be hooked up wrong.
