If you have narrowed it to fuel starvation as the prime supsect. The next step would be to verify your theory by checking the fuel flow and pressure to make sure they are both good at the fuel rail before the fuel pressure regulator. If your pump is making the correct pressure and sufficient flow. Then check the fuel pressure regulator to see that it will hold the correct pressure. If these things are all good. Then have a look at the injectors to be sure they are clean and flowing correctly.
