Default Fuel Pressure Readings

what is everyone getting for fuel pressure readings? I was getting around 10 when cruising and 5-8 psi under hard excelleration. I sent my adrenaline back (as did all beta testers) in to get the component added to my module and two or three nights after I installed it I was in bumper to bumper (which I am never in) and I started seeing over 20 psi while idleing. But when I started traveling again i was fine and withon my normal limits) and seems like after that I have been getting wacky readings. yesterday I was pulling some trees out of the brush and while it was idling I saw 48 PSi. This morning when I started it up first thing I saw 44psi. then while cruising it never got below 18psi.
is there a sensor issue or maybe a connection issue or a pump issue.

i'd lean more towards the sensor/quad issue.... i highly doubt that a stock lift pump is capable of producing 18psi reliably let alone 48psi and still living to tell about it.....

i would put a gauge on it before i would use the quad for pressure monitoring. Autometer, Isspro, Diprocal (sp) or even glow shift.... they have proven they work, and work reliably, time and time again....

its part of the adrenaline so I didnt have a choice when beta testing.

you could always run a gauge too so you can give them input on how acurate their sender is or isn't.

I have never checked mine on the Adrenaline I use my fuel pressure on my pillar gauge that I already had installed. I never even thought about hooking the Adrenaline fuel pressure up

Mine sits at 18 psi at idle, drops to about 13 WOT

just an update.
The issue was intermittent. so I figured it had to be a wiring problem. So I checked the connection and was able to get the reading to move. I added dielectric grease to the plug and problem solved. I get about 8 at idle
