Occasionally I do get high EGT lights. Fairly rare though, maybe twice in the last 5000 miles.
I'd love to get more power out of it, but not at the expense of mileage. Im also not in a hurry to get a hack to screw up my ECM. I'm currently keeping my eyes open for anything that could be lowering my mileage. I drive at 62 and for an aerodynamic truck, I'm still only getting about 5.5 loaded on level ground. Some of you get loaded what I'm getting unloaded(based on my fuel receipts, not the DIC)
Im still adjusting to it from the C15. The C15 was a bit easier to drive, and pulled better on the grades, of course the extra 150HP helps with that. Definitely have to shift faster. The lack of engine response under 50% throttle position is rather odd.

Just want to make sure it runs right and its reliable and not burning more diesel than it needs to...

EGT light comes on during active regen, it's normal.
Pyro meter and boost gauges will definitely help on driving it for better economy.
You're going to have to change your driving style compared to a Cat. The ISX is best not lugged below 1300 rpm and pulls better at 1600 on grades. Try that and see if your mileage increases.

Your own Insite is the best tool you can have, otherwise you're driving blind.
