    Are aftermarket fuel pressure regulators worth the price to get more fuel into the motor? If not, how else could i increase fuel flow to the motor?

    I really don't think an adjustable fuel regulator would be worth the money. But, if you plan on getting performance injectors and supercharging it in the future, then it wouldn't hurt. But unless you'r throwing more air in there, then you don't need more fuel.

    So since i am throwing more air in there(short ram intake), would i notice a difference by pumping extra fuel in there with the extra air?

    im curious about this to. i put a tbi spacer on my 4.8 recently and its trowing codes for lean mix. i like the little kick it gives so im trying to figure out should i boost fuel pressure ( and if so what the best way) or would getting me a tuner fix the problem with the code?

    thanks in advance

    Well yours is much newer than mine and a programer or custom tune would help you but for me, i'd have to get the new fuel pressure regulator.
