help please!!!!! no power towing!!!!!
1997 F250 7.3 auto trans
I went camping and my truck had zero towing power. I went from 1400' to 7000'.
I could not go over 40 MPH on steep grades. My foot was to the firewall!!! I think the turbo wasn't even spooling. Without a turbo would the truck be like this? Truck just would not go. I don't think I could hear it spool either. Vanes on impeller spin freely by hand and they are very clean. Any ideas? Thanks!!!!!

Could be an exhaust leak or boost leak. It definitely sounds like the turbo's not doing much.
You'll have to do some diagnostics. Do you have an Android phone or tablet? If so, you can get Torque Pro for like $5 and an adapter for $13 so you can monitor all of the engine parameters.

Oil level is fine. The orange rubber turbo hose may have been cracked. It was after removal but that might have been me wrestling it out. What is the difference of truck with and without the turbo?

How about the ebpv on the turbo ? It could be stuck on. Causing hardly any power. It's just a plug on the drivers side of the turbo. You can unplug it and see.
If your exhaust sounds like a jet engine then it's stuck on

So today when I drove my truck WITHOUT the trailer, it seemed fine. I went up/over steep passes with no problem. It is an awesome running truck as long as I don't pull the trailer. Is this year truck THAT underpowered for pulling an 8k load? I just assumed a 7.3 PSD could perform medium duty towing. Even an older model with 223k miles.

These trucks unmodified aren't real powerhouse's. They will tow anything but not fast. I like my obs truck and don't really care how fast I get there. There is ways to boost the power and probably a set of gauges, intake, exhaust and a ts chip will help a lot.

Your truck should pull an 8,000 lb load uphill just fine.
A PSD without the turbo will run worse than an old non-turbo IDI, because the PSD has lower compression to accommodate the turbo.
Set up a boost gauge or get the Torque app. All you're doing right now is guessing.
