About a year or so ago I pulled a trailer from here, Northern Cal, to Kansas City and back. Truck ran fine and pulled great, except when I got in the higher elevations. It would loose it's power big time, seriously go so bad it would loose speed while going down the grades. And smoke, boy would it smoke, left a trail for everyone to follow. I've read that the IDI can't compensate for elevation changes, that you have to do it manually at the IP.

Your water separator and your fuel filter are one and the same.

The air filter is critical, there is no such thing as "not that bad" when talking about a dirty air filter on a diesel.
Air flow is critical, both into and out of the engine.
A clean fuel supply is also critical.
The biggest power robbing part on your truck is the stock Ford turbo downpipe, a 2.25" ID pipe that they ran over with a fork lift 3 times before it was installed on the truck. Not near big enough to let the exhaust out of the engine, even worse after it was flattened out. The rest of the stock exhaust is not much better.
ATS sells a turbo outlet flange and downpipe that will let the engine breathe, and run much better. I understand it is a bit on the pricey side though, I think someone told me around 300 dollars.
