7.3L with dealer installed 'new' turbo - poor mileage
A while back, I posted about Dad needing a turbo for his '01 F-250 4WD crew cab (7.3L Powerstroke, 114K miles, automatic). The Ford dealership replaced the turbo (stock rebuilt Garret), 2 boost lines, and an oil line for a little over $3000. After the repair, he's added 2,000-3,000 miles, and the fuel milage is done considerably. Also, on really cold mornings, the turbo will chatter briefly before getting quiet. The dealership told him that the noisy turbo is common after replacement, and he's calling about the reduced mileage today. It may be just me, but after the new turbo was installed, it seems to shift out of 1st way too soon also - if turning out on the road, it's hard to get on it without it dumping into 2nd. Doesn't seem to pull as hard either. Does Ford dealerships re-flash the computers or screw with them after doing mechanical work? Thanks.

How "bad" is the mileage? What did he used to get compared to what it is now? They shouldn't have re-flashed the computer but may have not tightened something back up right and you now have a boost leak.
And new turbos don't make any more chatter sounds than old turbos do. Whoever your dad is talking to doesn't know what they're talking about. Time for a second opinion.

Just a friendly FYI, always check here from now on if there's any problem with that rig. There's so much knowledge here that it is crazy to go anywhere else first. Heck I bet somebody has a stocker lying around or knows of one that could have saved your dad a lot of money. Heck, he could of gotten a BB for less than half!

Dad checked the mileage yesterday - 15 mpg. Before, it got 17-18 mpg. As far as the noise, there are several people around Nashville who have experienced the turbo "chatter" briefly after starting it up on a cold morning. Next time that I'm in, I'm going to check a few things if the weather is good.

As far as I know, there is no such thing as turbo chatter. If a turbo chatters, it's hitting the housing and that ain't good. I have replaced my turbo with stock rebuilt one and if anything, it was quieter. Not sure what you are hearing, but have my doubts it's turbo related. Two miles per gal drop could be due to winter blend fuel. The lose in power could be due to a boost leak from poor install job. The other symptoms with the power could be IPR, fuel filter, old dirty oil and boost related. A lot of us run syn oil and that will do wonders for making cold weather starts much quieter. What oil line did they replace? Why? What was the issue that lead him to the dealer to begin with? 3k sounds extremely high.
