Turbo Issue?
2005 F250 SD, Crew Cab, Diesel 6.0L...
Hauling my jeep (close to 16,000 pounds all in F250+trailer+jeep) on a highway going a little over 70mph up a hill when I seemed to have lost some power and the check engine light came on. The turbo PSI was well over 20PSI (according to the gauge in the dash). I have a Scan Boss but I have not been monitoring turbo boost PSI.
I was only 10 miles from the final destination so I continued without stopping. It seemed that the turbo was limited for the rest of the trip. Later in the evening, no more check engine light but I haven't really driven the truck since then.
What do you think the problem was? What should the course of action be?
Thank you in advance for your advice.

Sounds like you may have over boosted. Watch VGT while driving unloaded, you shouldn't see 15 or 85. The VGT is a commanded value, not actual, if you see something like 20 and it doesn't seem to be giving boost and then all of a sudden it really goes, that may be the indicator of stuck vanes.

I'm thinking you got a defuel from too high ECT/EOT delta's, which might indicate a plugged oil cooler. You need to monitor ECT/EOT temps and see what the difference is: not towing, on level ground, for at least a 10 mile run AFTER the engine gets up to FULL operating temperature.

There is a chance it's the oil cooler but presuming you've been monitoring that it's about 99% sure you have stuck turbo vanes. I had exactly the same symptom, pulled turbo, it was heavily rusted so I got a new Rotomaster replacement. I didn't want a third Garrett.

NPCCPARTSMAN,
My ECT/EOT deltas are not a problem. Even when hauling 16,000 pounds total up hill on the interstate deltas were not over 8-10 degrees. The oil cooler and egr are ~ 3,000 miles new. The rig has 103,000 miles total.
