If you think youre going to have to change the fuel pressure then yes, you need an adjustable regulator

From what I have heard, a lot of dyno shops won't even touch a car (to tune it) unless there is an AFPR on it. But I can't confirm it. It's a good idea though.

You do not need an afpr if you're getting a chip tune or any tuning device. Unless during your dyno tune you notice the injectors near maxing out, you can raise the psi a tad to decrease the duty cycle.

Fwiw, I have an anderosn pms and a wideband. I tune myself on the street. I run 40psi fuel pressure.

Yeah, no need to increase pressure unless you are out of fuel. The computer can be programmed to the right amount of fuel through injector pulse width. No need for the regulator.

Tuning a car by the regulator is pointless. It won't make any permenant changes.
