You don't. Its a fully electronic controlled engine, so the idle is completely controlled by the PCM. You can have tunes written for it though, and have the idle changed.

Why do you think the idle is too low?

Your friends Cummins also has 2 less cylinders, and they are all in a row. So don't compare how his truck runs, to how yours runs.

What is your 7.3 idling at right now?

Thats right on the money. The Cummins is totally different. I think my dads idles at 800rpm. Which is why if anything the Cummins should come down 200rpm. I personally think they idle a little high, but hey it works. lol Our Combine idles at about 875-900. It has a Alis-Chalmers 3500 Turbo I think. Its like 7.9 liters(maybe even 8.2), and it only produces 140-200hp. Our John Deere C-450 idles at about 600-700rpm. It's a 4-cyl though.
