Do I have to swap out my ecu with this plan: Swap manifolds, injectors, map sensor, and intake plenium.  Do I have to swap out the complete Ecu or can I add a 3.1 Turbo PROM?

Will an electronic boost controller control this?  Is there any way to keep it stable(no boost spike)?

I am planning on doing a turbo swap on my 3.1 beretta.  I am switching out the ecu, manifolds, injectors and map sensor.   I will be able to run 7 psi safely on this setup.  My question is, Is the TGP T25 Acuator adjustable to run 5psi Daily?   I am installing at AVC-R boost controller, but I need to lower the set boost so I can run around 4-5 psi daily and run 7 psi when racing.  Thanks For Your Help!
