It takes up one of your already limited input's with the term x, only real advantage would be for data logging to see if you have a fuel supply issue under load.

the fuel pressure doesn't take up any inputs, it is nice to have for fuel pressure monitoring, you can also setup a safety with it. I don't think the term x uses the fuel pressure for any fueling calculations. A $10-50 sensor and some table scaling you could have actual pressure displayed is pretty easy.

Are you running a boost reference 1:1 fuel pressure regulator?

Mine has the factory 2001 truck intake with the vacuum regulator and return line.

it would probably be helpful to have the fuel pressure reading just to keep an eye on it. i believe there's an adapter fitting on the market for the fuel pressure schrader valve to 1/8" npt thread.

My bad, I've been looking at so much different holley stuff lately I don't know why I forgot the term x has the provisions for it built into the harness. So with that being said like akdg87 said, pick up a sensor, I recommend looking into low dollar motorsports for a sensor vs an over priced holley sensor. It's a handy thing to have for sure.

Gentlemen,

Only just discovered there is an LS section on the board so a bit late to the party!

Unlike the OP I am new to Both LS swaps and turbo but have been learning as much as I can over the past few years so when I started back on my truck last year I had the majority of parts and knowledge to get to the burn outs and ice cream stage as quickly as possible..

If you have not watched Matts series yet I would highly recommend it

Also watch this.

Bit out of date now but it is what I am using as my build recipe

Look forward to following your build.
