Edge Evolution showing DTC codes but STC tuner not.........???

So just like the title says....I have an edge evolution that keeps showing up with code P0673 (#3 Cylinder Glow Plug Circuit.) I also have the SCT tuner (I leave the edge evolution at 0 and use it strictly for monitoring) and the tuner keeps showing up with no codes when I check for them. Anyone have an idea why? My check engine light is not on either and the edge has been updated with the newest firmware and is still showing the code.

Truck is a 2005 6.0, 107k, and part of me thinks there could be something wrong with a glow plug since it usually take 5-6 seconds of cranking when the engine is cold, and if it is in the teens it can take up to 10 seconds before it turns over......usually no rough running except the one time I started it, not plugged in, and it was 5.......took a few tries before it would turn over and keep running but that was only 1 time.

The SCT cant scan codes for crap, i dont know why but it cant... mine doesnt read and i have a CEL for egr flow and no valve with my egr delete... my old insight did. Just the way it is

you could need a new glowplug, also check for wire chaffing.
