I got it back on the road today. Mileage isn't great, just under 18, but I have been doing alot of short trips around the neighborhood playing with the tuning. I decided to re-plumb the air system for the afc and try to run if off the low pressure (cold pipe) side instead of manifold pressure. It's going to take a bit more tinkering to find just the right spring. It's still a bit tight right now and isn't allowing full arm travel till about 35psi(cold pipe). The injectors idle clean with the engine warmed up and an outside temp of 84 degrees. No visible smoke. I followed an older powerstroke into town just now and going up a modest grade at 62mph he was smoking alot more than i was. I did a couple of lazy 3/4 throttle roll ons from 70 to 110-120 or so and there is some haze, but it does not black out the road. I didn't try full throttle, but i can tell the fuel is lagging slightly behind the air. I looked down on the last run and saw the pyrometer was at 1200 just as i backed out of it. Hopefully i'll get some numbers toward the end of the month.
