old post but for others wondering down the line..
a boost controller, whether manual or electronic, will only be able to raise the boost level.
If you are having issues with overboosting you need to investigate the wastegate.
If it is not a stock wastegate it may have come from another car...
If you unplug one of the wheel sensors it should disable abs and cause light to show on dash.
If it drives normally in that state and brakes are not "locking up randomly" then you at least know its most likely something with the abs and not caliper/brake line stuff.
I am not familiar with doing a swap in a v6 but some things to keep in mind:
Transmission mounts may be different
Brake components for the hydraulic clutch hose
Axles - different from auto to manual?
Flywheel/clutch in good shape?

You will want to hook up boost gauge and bypass or blow off valve to the intake manifold as well. You can buy vacuum line for hooking up these devices from most part stores.
