Please explain..what is the reason most ppl buy an Aeromotive or any other aftermarket 1:1 adjustable FPR on their turbo cars if the Stock OEM FPR is already a 1:1?

So they can adjust base fuel pressure?

Then why not just use a B&M or Vortech Adjustable FPR that mounts on the factory one?

Same thing IMO..

I guess there must be some other stonger reasons to do it...Besides the Bling..

you pay what u get for, its the quality and the reputation u pay for. and you know it will work good

I think the aeromotive FPR is much better then the B&M and vortech which you bascially just cuts the top off of your stock fpr and uses theirs. That't not to say those are not any good. I had a b&m and never had a problem with it and also had an AEM which are known for the diaphrams ripping.

I had to take off the aem when I put my jg manifold on b/c the return line was kinked.

I think most people run aeromotive becuase you can run a larger fuel and return line and also use all ss lines with fittings if you are using an aftermarket external pump, plus not to mention you really never hear about them failing.

I can understand this if someone is going to run a lot of boost..but what if the person is just going to be boosting 10-12 PSIs?

I could be wrong but with a larger fuel pump and larger injectors you want to lower the fuel pressure to even out the spray pattern and to get it tuned properly. The B&M regulator can only raise base pressure it can't lower it.

the b&m is also very inconsistant, while "adjusting it."

Not all OEM's are 1:1. I had a couple that did not increase fuel pressure under boost...and a couple that did. Even the ones that did were not 1:1...they were more like 0.6:1.

I, too, though that all OEM's were 1:1 until my in-car full-sweep fuel pressure gauge proved that wrong.

In addition, with a lot of the aftermarket pumps, you cannot get your idle pressure low enough (ie, 35 psi) with the stock FPR.
