Help diagnosing my F800 dump truck

Hey guys, I'm new here so I've been going through different threads and can't seem to find what I'm needing... Anyway i have the 2004 F800 dump truck with the 7.4L V8 n/a engine. When i first bought it there was plenty of power and even though it didn't go up mountains like it does now i never really had issues when it was under a load. Just recently it started smoking, the transmission started making a weird grinding noise and all around struggles. It had a miss in a cylinder that i fixed changing a coil pack which helped some but still having problems, my friend mentioned to hookup a computer program to it tune it for turbo and turbo charge the 7.4L, what's your opinion on a 200,000 mile 7.4L engine and adding power for my overall payload?
