Pressure Test Help

[Gokiwi64]

So I want to do a full system boost leak pressure test.

I have made up an adaptor to fit where the MAF goes but what pressure do I charge the system with ?

I know I need to remove oil filler cap , although I have a vent to atmosphere catch can.

What else is needed ?

Well, the results are in and they are not good, not good at all.
So essentially the first attempt to do a whole system pressure test failed ,found the IAT sensor in the throttle body leaking badly so fixed that.
Next it still wouldn't hold 15 psi , it leaks down very quickly , tracked it down to the dipstick tube , so with that blocked and the oil filler cap in place it still wont hold pressure.
