What do you mean exactly?

Timing is 10deg BTDC for turbo and older NA engines and 13deg BTDC for newer engines. You check this by removing no1 pipe from the injector pump and rotating the engine by hand until fuel first starts to come out.

If you mean fuelling, then check the intercooler thread.

Truck and military LR engines have 85Bhp at peak revs and civvie LR engines 99Bhp. I was quoted $500 from a fuel injection place to mod an 85bhp pump to a 99bhp pump.
