Fuel Regulator Question:

I just got my T-trim on my car. I'm running a Paxton fuel pressure regulator (just like the Aeromotive A1000). I set my fuel pressure at 40 with vacuum disconnected. I'm not seeing exactly a 1-1 pressure increase with boost like I thought I should. At 10lbs boost, fuel preesure goes up 8lbs to 48. Is this common with this regulator? I'm using dual Walbro GSL392's, -10 from pickup, -8 to the rails, -6 return, so I don't think fuel supply is the cause. Any help would be appreciated.

Thanks!

I don't think they are exactly a 1:1 but usually close. So you should be fine. Seems like it is working.
