And because I felt like it, I ran fuel economy data after the tuning I did this past Friday. When I fill the tank for fuel economy data, I fill it all the way up into the filler neck so there's no question the tank is full.

This time around I did 76.0 miles (actually clicked over as I parked at the gas station!) on 2.862 gallons of diesel. That comes out to 26.55mpg, 100% stop/go "city" traffic with A/C running. Unlike the previous time, I drove like a normal person without romping on the skinny pedal.

I think my tuning is complete! Plenty of power without any smoke, and now very good fuel economy. My Honda does ~22mpg for the same driving for comparison. And it's A/C isn't as cold!

Just goes to show that yes, the 3.5L injection pump CAN be used in a 3.0L engine, but needs to be tuned for best results.
