Here it goes, i was wondering if anyone else has seen this. When the truck warms up I have eng. temp on the attitude and it seems like its about 30-40 degrees off what the factory dash gauge reads until its warmed up and it seems fairly close around 185-190 or so. the attitude is consistently reading lower. so i never really thought it was an important, send back to edge problem. let me know what you think.

Factory guage problem not an attitude problem. I beleive the attitude.

I just got a Juice/Attitude (2005 LLY) and noticed the same behavior that you experienced. The person who installed it hooked up a scanner that displays the engine parameters realtime. We used it to look at what the sensor was reporting. The Edge is correct, and the factory guage is incorrect.

Based on what was reported by the scanner, the guage gets close to the correct reading as the temperature approaches 200 degrees.

Remember, this information is worth exactly what you paid for it and as always YMMV.

for piece of mind, mine does the same thing. i figured that the edge attitude was correct over a gauge from the factory. looks like this was a good assumption.

Same here. Probly the same group of people that made the fuel gauge!

here's a theory that the factory gauge is mismarked!
