I can't see any good reason for getting one. It's not useful for tuning as it is a blanket increase in fuel across the board. If your injectors are reaching their limit duty cycle at high RPM's, you need bigger injectors. That way you can increase fuel at high RPM only w/out killing your idle and cruise air / fuel ratios.
Don't make the mistake of thinking "I have an intake, exhaust, header, and a cam, so I need more fuel". The end result of blindly increasing the fuel pressure is that you will lose power, increase your exhaust temperature, destroy your cat, fail emissions, kill your gas mileage, make your car smell like ass *cough gas, and have popping sounds from unburned fuel igniting in your exhaust pipe. Did I mention LOSE power?
The truth is that running a little bit leaner (under heavy load and high engine speed) than the factory calibration will give you more power. But you better make sure you know what you're doing or you'll destroy the motor. Honda, just like everyone else, runs safely rich at the expense of power.
In short, I have seen many Hondas make tons of power w/out adjusting the fuel pressure. When you start getting serious about modifying your motor, there is only one thing you can do. Get your car on a dyno and tune it properly. Whether that is a standalone, re-flashing the stock ECU, or a host of band-aid, external controllers. You need a wideband, you need to be able to measure power, and you need an accurate representation of what your sensors are reading.
