Becasue the Comptech FPR is a rising rate FPR. Basicly as it sees boost it increases fuel pressure. And it's not really accurate, so tuning with the EMS because a nightmare, because your FP will never be the same. With the AEM FPR it's a contastant FP, but adjustable so you can dial in the FP...but it never changes after it's set.

This is why I asked, I read somewhere that you can remove the Vacumn line to the Comptech and it becomes a static FPR instead of a Rising rate FPR but I do not know if it will be a 1.1 ratio - I wish somebody knew this because this is getting expensive
Nick, I needed that! After spending what's you've spent on the motor...Anyways, I needed to chuckle.

The comptech FPR is adjustable as far as the ramp up rate goes, and I would consider it a better unit than the AEM FPR.
You are going to want a 1:1 rising rate anyways; stick with the comptech unit, just figure out how to adjust the ramp up rate.

Ztec, the comptech FPR is 1:1 with no boost pressure. This is why the car "feels" stock to everyone down low, it's basicly is. You can get the B&M AFPR a lot cheaper than the AEM one, but with that you have to use the bottom half of your stock FPR. Do a google and look into it...a lot of DSM guys use it.

Thank you, I am familar with what a fuel pressure regulator is, and the Comptech unit that he already has is a much better unit than the B&M or the AEM.
The comptech unit can be set to a 1:1 rise rate.
Don't waste your money on the B&M unit.

hmmm me thinks I might have missed the original topic here...I thought he was wondering if he needed a AEM FPR because of wanting to increase the FP.
Ztec, if all you want is 1:1 FPR than yes the comptech will do (as will the stock unit)just plug the nipple where the boost line was hooked. If you need or want to be able to adjust the rate, then you will have to run something other than the comptech.

Well if you would have mentioned it does both rise and ramp three postes ago you could have saved yourself a head ache from all the
And I appoligize for not knowing you could set a static rate, I've only have experiance with the vortech unit..I should have looked into it before posting.

I appreciate you guys going back and forth actually
It is my understanding that if you cap the vaccum line on the Comptech FPR it becomes a static FPR and it is adjustable with the allen set screw on top - Clockwise ups your fuel pressure! If this is the case I do not need to purchase another FPR correct?
