1997 f350 slow to boost and lacking power when warm
My 1997 f350 was leaking where the manifolds met the up pipes. The truck struggled to go until about 2000 rpms and then it pulled much better. I had the manifolds and up pipes replaced and the truck now pulls nicely when the engine is cold. When the truck warms up, low end power is sometimes lacking and the truck seems to shift too soon, which makes the truck bog down. Any help would be greatly appreciated.

Over drive light on shifter is not flashing. It starts fine when the engine is warm. Turbo and exhaust gaskets were replaced when the manifolds and up pipes were done. I'll check the oil level tomorrow. Maybe I'll change it this weekend just to rule that out completely. Does this problem have anything to do with the oil warming up?

I changed the oil and oil filter but the truck is no different. It revs fine in neutral. It just seems to not boost much until around 2500 rpms. It struggles to accelerate uphill. I changed the fuel filter in the spring and don't remember the fuel being black. I will check tomorrow after work.

Changed the fuel filter. Didn't seem excessively dirty or black. Put the filter in a ziplock bag to see if any oil drained or separated from the filter into the bag. None did. Any other ideas? I'm thinking maybe I should pick up a code reader to examine further. I'm worried that it might be a compression issue.
