Thanks for all the tips. First thing today after work I'll unplug the backpressure valve and see if that helps. If I leave it unplugged is there any reason to clean the sensor tube?
I've read the 7.3 was a slouch but I wasn't expecting this. My wifes Tahoe hybrid can pull just as hard haha. I gotta get it fixed for vacation this weekend. I'll be pulling the trailer up to 6500ft.
Reliability is the strength of the 7.3; they definitely don't compare to the new diesels with regards to power. But if you're saying your gas powered Tahoe tows comparably, I'd say there has to be something robbing your truck of power. My wife's 2001 Excursion 7.3 is bone stock and I just pulled a 24x8.5 enclosed car hauler with an El Camino inside (roughly 7500-8000 pounds total) 700 miles round trip and it pulled well. Don't get me wrong I felt it back there, but I never felt like I was underpowered or couldn't pass a slower vehicle.
