[quote="Dave"]Chad- yeah, but all engines get a little dirty. This one looks like the PO got a toothbrush out and spit cleaned it while the oil drained during oil changes. Friends don't let friends blow up their new trucks.
You are not use to non old-n-busted. I've never taken a rag to the mazda6 engine and it's spotless, the expedition isn't but only due to the numerous mud holes, no grime, just burned mud. If I had a 7.3l I wouldn't hesitate to throw a tune on it, those trucks are made for it and really respond well to them. They are so mature the mail order tunes are pretty much fail safe.
