i dont think you can adjust the fuel pressure with the stock one.
unless you use a b&m which hacks on to the stock one

Not sure what he meant by this but the stock fuel pressure reg is NOT adjustable, the B&M FPR would be as close to stock as you can get and still be adjustable. The only other way to do it would be to use an APEXI SAFC and tune your fuel curve that way. It would certainly be more accurate because with a FPR if you reduce fuel pressure you'll remove fuel across the entire fuel curve and the opposite is true if you were to increase pressure. Most power curves need less fuel in some areas and more in others so an adjustable FPR is not the best way to tune your car's fuel curve to make optimum power.
