Re: Adjustable fuel pressure reg

No gain unless you are running lean up high due to mods. Because wide open throttle relies on set fuel maps and not input from oxygen sensors, if you do a lot of mods you can start to run lean. Upping the pressure just allows more fuel to be delivered. Won't really affect anything except for full throttle though.
