No pulling power

Yesterday I noticed my truck was noisier than usaual I didn't think anything of it I hooked up my gooseneck and away I went the first hill I got to I had no power the truck started to vibrate real bad and slowed down to about 10 mph it started to run like it was out of fuel but its not alot of stuttering. 2003 7.3 with power hungry tunes dieselsite cpr bts valve body and a new ford trans. Iam thinking turbo or injector

Need to check fuel pressure, ICP, boost, and do a couple cylinder tests.

So was the boost low with trailer on and off? Any smoke out of tail pipe?

The boost was really low the trailer and with the trailer under extreme conditions up hill say real low boost vibrating I thought the truck was going to stall out without the trailer you can drive the truck all around the injectors soundvreal loud and when go WOT it feels like it way down on power and boost is low but not as bad

Ok well there may still be another issue causing the low boost.

I listed what I would check first.
Boost, ICP, fuel pressure, cylinder buzz and contribution tests, even MAP and EBPS readings.
