Messing with your fuel pressure only serves to throw off your closed loop fuel trims. This is by far the worst way of tuning ever. Your car has electronically controlled fuel injection, which happens to be tunable electronically, please don't tune it like it has a carburetor.

Plus I'm pretty sure our fuel pressure regulator is located in-tank along with the filter and pump.
