Fuel pressure
My 05 has Glowshift gauges on the window pillar. All are analog except the digital fuel pressure gauge. It almost always reads 102 and that can't be right. Sometimes when idling at a stop light it might go down to 95 for a few seconds.Any ideas? Maybe wire grounding out from sensor?

So, I am curious as to whether you got this resolved or not. I just installed a GlowShift 3 in1 and the digital fuel pressure reads 72+/- psi. Seems high but perhaps that is alright? Thoughts? Thanks, gm.

My digital fuel pressure gauge (SpaTechnique Gauge/Sensor) reads mostly between 64 and 75 - so 72 isn't abnormal. I would assume you have done the blue spring mod (which replaces the origin fuel pressure spring with a "blue" one that dumps up your pressure).

Haven't had the chance to troubleshoot it yet, vacation starts tomorrow after work. Hope to play around a bit with it, order new K&N filter, don't know how long the current one has been on the vehicle.

stock is acceptable up to 500HP and filters the best.
our sensors do not like the oil that's in the K&N and our turbos don't like the extra particulates they let slide on by.

I have been looking for a stock intake assembly. Mine has the K&N CAI. If I could find a stock setup I would go back to it.

Easy rough check of a sensor like this is to install it to a air chuck fitting and see if it closly matches a regulated air pressure. It's a rough check only.
