tfunk: Just some values off my gauge for you: idle: 60-62, running at mid to light throttle: 58-60, WOT: mostly low 50s, but I have had a few where I've gotten it down into the high 40s. The absolute lowest WOT pressure I've seen is 47. I have a GlowShift gauge and haven't compared it to anything else. I was expecting higher readings, but who knows if the gauge is accurate, or maybe my bluespring is tired, or what. Right now I plan to just watch it...
Good luck with yours!

I have a glow shift gauge as well. Thanks for the info!
Jack, you may have been on the money with saying the new pump may need to burnish the brushes....seems to be holding better pressure today. Like, what would have gone down to 55 yesterday was 58 today. We will see.

Edge CTS3 with the Edge 0-100psi sensor. Still need to check it against a calibrated gauge to see how far off it reads.
Truck is stock with 1-year old blue-spring kit. Assuming pump is the original with 115k miles on it.
