Resolved Setting fuel pressure with SX AFPR

[BINGchndlr]

I just installed a SX Performance AFPR and gauge today but I can't lower the fuel pressure back to stock.
I can back the adjusting screw all the way out and it'll still be above 30 psi.
Am I doing something wrong?

It's a B&M gauge

thanks

Is this with the vacuum line attached or disconnected. If it's disconnected (which it should be whie adjusting fuel pressure) You should be adjusting it to 37 psi anyways.

Here read this it may help you out some. If you have a logger and all you may want to adjust it such as this guy did until you don't have an increase in knock. If it is fine at 37 psi leave it there.

Yeah, also remember to always set the base fuel pressure with no vacuum to the FPR. It will drop once vacuum line is connected.

I turned my base up to 44psi and tuned out the extra fuel with my SAFC2. It'll give you a little more available fuel up top by increasing the amount of fuel available going out the nozzle for a given pulse width.
Gotta squeeze out what you can with stock 450's
