Hi all. New member here to the forums and to Diablo products. I just put the Trinity and EGT option in my truck, a '04.5 3500 cummins, my question is what range should the temps run... I get about 140 at idle and if I get onto her it has jumped to 500+. Are those normal ranges and should the egt guage go up and down as fast as a tach or did I do something wrong in set up? I really like this thing the extreme is alot of fun but I think I will be running tow most of the time. I worry about the truck and just want to make sure things are working correctly. Thanks

That sounds a bit low to me...

Normal temps would be about 250 at idle and 1500+ on extreme. When you get on it, the temp rises quickly but my '05 is slow to cool back down. May be a bad EGT probe or wire harness.
