i just swapped out my turbo for another stock one and now im only hitting 13 psi. does it just need broke in? or is something wrong?
i also put a turboxs uppipe on and already have a TBE.

the stock one i got is used. the guy i got it from said he ported the inlet and the wastegate

also i check the connection on my bov and it was leaking. i fixed that and now it spools to 16 psi drops to 12 or so and then goes to 14 and stays there

how do i do a boost leak test?

its pretty simple if u have the right tools, if you google boost leak wrx will see one forum where they have a good example of doing a boost leak.its basically pressurizing the system from the turbo inlet hose with roughly about 30 psi then listen carefully for any leaks if there is you will definitely hear it.
