Hmmm... Doesn't the ecm have to re-learn your driving style after the reflash? I'd give it a little time...

With that drastic a decrease in egts - maybe this reflash does a bit to reduce overheating as well. I'll take a little less power for an improvement in fuel mileage and cooler running. How drastic a decrease in power is it?

Mine goes in next week for the reflash...

Just curious - since noone else has reported a problem with the reflash - maybe something else changed and it's a coincidence that you are seeing a problem. If I was in your situation, I'd check a couple of things before "flashing it back" - I would change the fuel filter and add some good fuel additive to see if things "look up". Stanadyne performance formula is my choice for an additive.

After a few miles with a new fuel filter and additive - then you'll know the injectors are squeeky clean and lubricated and fuel is flowing at a good rate towards them.

ecm reflashed with 15141688
What does this flash address:confused: I don't see it listed as a part number for the current updates. the newest part number/flash (for the intake pop) is 15904640. I don't see the number you gave for any lly calibrations

Funny thing is that looking at the new calibrations beside the old ones they didn't do anything to decrease power. Not sure how to explain it but it doesn't make sense.

Maybe you got bad fuel or you are running a winter blend or something??

Or they messed up doing the reflash.

Some of these dealers have others then Diesel tech doing all the reflashes.

You can't really do much wrong.
