Default should i get an si/ex fuel pressure regulator for crx manifold or aem adjustable one

ok so i think im not getting enough fuel to the injectors on my d16y8 ,cause its feels like its missing some power, and im thinking its because its an hf intake manfold or which ever one is multipoint fi. i read somewhere on a swap page to get a fuel pressure regulator from an 92-95 ex or si system and id really like to do that over buying one of those adjustable fpr's on ebay, cause im afraid of setting it too low or and the same place or way to high, and i dont want to destroy my gas milage, i dont know how fprs work but im thinkin the ex/si would be smart and cut itself down at the right times.

i would appreciate yalls opinion greatly

To avoid setting it too high or too low you should install a gage on the fuel filter and check pressure before swapping regulators. Install the new fpr and set it to the pressure you observed before the swap. Then go from there. Gas mileage won't change much if you bump up the pressure a couple psi.

You won't be disappointed with the aem fpr.
