Lol! I knew there'd be more questions than I could answer, but I can't even answer the first one. Ok, can you give me a list of questions to ask? I'll get the answers and come back, but it won't be immediately as I'll have to call him tomorrow. Again, thanks in advance. I appreciate the help already.

Is it blowing off boost through the turbo? Better heard without the aircleaner and short drive? That's the turbo,either solenoid not working or vains sticking.
Low boost numbers with a power brake is a boost leak.
Low boost while driving/towing is also a boosts leak.
Try these out,I'm more a 7.3 guy,but fiddle with all of them. Hopefully someone will come in and help more.

Ok, I will try those on him. But, he did say it only happens when towing - either with the stock trailer loaded or not.
Thanks again.
And, btw, he has an 84 F250 with the 6.9 that he says he would sell me "cheap", so I'm also trying to learn about diesels.

Talk to Buddy get Exact DTC/Code
For Now we can assume its the P0299 DTC
Being an 06 tell Him to Clean the EBP Sensor and Tube to EBP sensor. To find The EBP sensor Locate the Driverside Exhaust manafold there will be a Metal Tube (Like same size as a Straw in a Big Gulp) coming out the Exhaust Manafold Follow it till you reach the EBP Sensor and clean it
To really even have a Chance at a Fix without just throwing Parts with a Prayer at it he needs a gauge to read live sensor Data
Alot use a ScanGaugeII me included He can get it at AUtoZone he will have to enter some Data into it But it will read All Engine sensors the PCM uses to Calibrate the truck
With a Digital Gauge we would look at
BARO
MAP
EBP
VGT%
BOOST PSI

Benny - I have a PLX scanner that works with the FuzzyCar app on my phone. It gets live data on other vehicles, including the motor home with a V10 I tried, so should work on his.
And, I will tell him to clean the EBP sensor and tube. Thanks!

Well then check the EBP Sensor output with the Gauge before cleaning EBP sensor
At KOEO there should be No More than .5volts diffrence at that time between
BARO
EBP
MAP
Also check those at Low Idel and High Idel (2500RPM) TRUCK IN pARK OR nUETRAL During test Not driving
Might be Hard to see since issue only comes up when towing. And he might have to tow to recreate the problem and check Numbers at that time
Maybe just get the numbers for those 3 sensors (3 Values per each sensor) and will seee if something stands out for Now

Ok, works for me. But, the truck is in TX headed away from me as his SiL is towing a boat down for a fishing trip. So, it'll be a few days before I can check it. Bit thanks to y"all I have something to check.

And, I know you are going to think of me the same as I did of another guy earlier today when he said he doesn't know the difference between a voltmeter and an ammeter. But, what's a VGT? Is that what needs to be cleaned to solve this problem? Sorry to be so dense, but I'm lost and don't know what to tell him.
VGT is Variable Geometery Turbo. Unlike older hair dryers, there are vanes inside the exhaust housing side of the turbo that will move/sweep to create the most boost possible; regardless of engine RPM. Older engines the exhaust pressure had to get up to a certain point to create boost on the intake side. That's how the 6.0L has a wide power band...and I'm sure it helps with meeting emissions.
Hey Benny, I wonder if the vanes are stuck and could be loosened by an Italian tune up?
