boost cutquestion all ready did pressure test

[lian]

ok so im trying to eliminate all leaks im hitting fuel cut at 14 psi.
so far i have checked the exhaust replaceds some studs for the manifold,i pressure tested up to the throtlebody and elimanated small leaks but i am still hitting boost cut .
i need some more ideas on what to look out for if its not the intake manifold that has new gaskets.
and how do you presure test or find leak from the intake maifold or all the hoses running from it.
and my turbo is in good shape didnt find leak around it

Fix the codes first.

Also, you can pressure test the whole car if you leave the oil cap off so you dont build crankcase pressure. It will let you hear if you have vacuum leaks in other places.
