Adjustable Fuel pressure regulator, which one

[tch777]

Okay guys I need a clear opinion.
I am buying a high flow TBI from ExtremeFI.
Its the 46mm 590 CFM unit for 199.99.
I am also going to buy an Adjustable Fuel pressure regulator.
They have an adjustable one for 39.99 or a vaccum referenced adjustable one for 59.99?
Is the vaccum referenced worth the extra 20 bucks?
I am leaning towards it but never really saw a clear comparision on this site as to which is really the best one to get.

Thanks

Tim

Is this thing on?

Hello no one here has installed either adjustable fuel pressure regulator?

If you do a search you'll find plenty on this. It's been covered quite recently. I've got a Jet adjustable one but I'll be changing soon to a vaccuum referenced one because of what I've read on here!
Have you got a link to the one you're thinking of buying?

here is a link to the web site of the place that sells the Vaccum referenced unit.

I looked thru his ebay auctions, but the Vaccum referenced adjustable fuel pressure regulator was not listed. So I emailed him. He is going to set up an auction for me so I can buy one from him. I already bought the TBI and it is on its way.

Before you dump $199 in a high flow TBI, I've got a 454 TBI for sale $170 shipped:

Thanks for the link. I'd be interested to hear what difference the throttle body makes.
