As you PM'd me but asked basically the same thing here, I'll answer it here...
I can assure you the phase 1 T4 will generate about 14psi as standard. Mine is phase 1 and mine did have that as stock. With the MBC I have turned it up to 1.3 bar about 18psi. You mention concerns about modifying the output and engine wear, well certainly anything done is at your own risk but plenty of others have done this and chipping the engine will I am sure raise the boost to at least these levels. You have the dump valve so no issues with the air recirc valve struggling to hold the pressure as you have presumably removed it.
