A Reflashed ECU (when you have new data put on the ECU to account for different mods) changes internal settings like fuel, air flow, injector duty, etc., boost. You can also take a bunch of routes you just get a boost controller, or a new stand alone engine management system (only for the serious power nuts), or you can use piggy back systems like the apexi s-afc or the greddy e-manage system. These piggy back systems let you make changes and tune your car, so a piggy back system with an electronic boost controller is another way to go like getting the Greddy e-01 boost controller and the greddy e-manage unit or getting the Apexi S-AFC and the Apexi AVR-C boost controller. With these systems you don't need to reflash cause you can just retune with your electronics anytime. I am partial to using the piggyback systems, just my take.... Depends on what you have done and what you will do in the future. To me reflashing seems good if you do things in chuncks but like most people who get parts over time one by one reflashing my get annoying. Easiest thing is to just get a manual boost controller for $70-100 and run 15.5 psi, that way you will stay inexpensive and gain a good bit of power. But as I said I would get the electronics I like the Greddy duo.
