Re: 2000 7.3L ccsb poor fuel economy and low boost
Re torque the up pipe bolts, PITA but can be done from under the truck drivers side, through the passenger wheel well other side.
After a few heat cycles they will be loose around the gaskets
Remove, inspect and clean all intercooler boots clamps and piping. A very good idea when you get a new to me old 7.3 truck
Do the same on the intake/air filter side of things
Check turbo impeller for play. A tiny bit of play side to side is okay/normal (not enough to hit the housing) any play in and out is not acceptable
