I dont know the answer to your question, as there are many variables, but I think your mistaken about it running at 14.5 at WOT. That would be disaster.

I think you will need more fuel for the added boost than your current system is capable of, so I would say you are going to need bigger injectors and fuel pump. Personally I don't like boost a pumps, many do, but I don't trust them. It's too much of a Band-Aid and not a real solution for the situation.
