Sooooo I am having probs with my RRFPR...i think. My fuel pressure is not staying steady at idle and goes WAY up past 10/1 on my wideband under boost.. Anyone know of a GOOD RRFPR that lets you DELETE your stock fpr??

I dont use my stock FPR.. You may need to get an adapter from MBX motorsports. problem is.. Im not sure if it will bolt to a b6 fuel rail.

Ouch....
Multi Role Regulators
The new Multi Role regulator from BEGi is designed to provide complete adjustability to your fuel injection pressure. The MR series takes all of the features found in our rising-rate regulators and adds the extra functionality and convenience of allowing you to adjust your base fuel pressure (the fuel pressure at fuel rail during idle conditions). This allows you to replace your factory fuel pressure regulator with a fully adjustable, easy to mount, single unit.
Patent Pending

Price $309.00 (Fittings included)

MR2032 Factory (OEM) turbo and supercharger applications
MR2033 Normally aspirated applications
MR2035 Aftermarket turbo and supercharger applications (1/8 NPT)

It was designed to replace your stock one. Just since ours is fitted directly to the fuel rail, you have to remove it and need an adapter. Mines a rise rate based off of vaccume, I assume yours is too.

Check out synapse motor sports (I think that the name)
For an adjustable RRFPR.
You can adjust base pressure and the amount at which it rises.
but you dont have to replace diaphrams.
Just a turn of a screw.

Take your rail off and get it tapped. Then you can put a fitting in there. Thats what I did and it works perfectly. If youd like I can snap a pic for you.

How bout saying screw the rising rate and just use my afc to adjust? Im runing 320 cc injectors and i wonder if the afc is fighting with the rrfpr for adjustment. THOUGHTS???

thats what it sounds like to me. i drilled my stock FPR out so its there but flows like a mother fo. i was running a cheepy MSD one and it worked great, now i have this bad a-- comp tech FPR to go with my stand alone.

No problem with flow. Just cant seem to lean her out.

The cartech you have IIRC should let you set static fuel pressure at idle. I used to run with a 2025 wich is the same as your 2027 except with 1/4 fittings instead of 1/8. I was not running with a stock FPR at all. The screw on top let's you set the base fuel pressure and the knob on the side let's you set the rising rate. It's kind of like having a FPR and a vortech fmu.
But seeing how serious you are with your car, even thought of making the big step like in standalone ?

I thought the 2025 is DESIGNED to use the stock fpr.

then what would the screw on top do ? IMO the screw on top acts like any other aftermarket FPR
