New Member doing Diesel Upgrade

2000 F250 Extended Cab
7.3L, all factory at this point

I'm new to the group. We used to get around 20 mpg hwy with the 7.3, and that has dropped to 16 av. We're lucky to get 14 around town. When the truck was under warranty and we took it back to the dealer with a complaint of poor mileage, he would reprogram the Power Control Module and the mileage would be restored. I've been looking at various secondary market programmers and exhaust/intake upgrades with the idea of improving fuel mileage, and most manufacturers do indeed advertise an increase in mileage.

I've read a lot of postings in this forum suggesting all sorts of tricks to improving fuel mileage, but none really addresses my question: Can anyone recommend a combination of programmer and intake/exhaust that has successfully boosted their mileage?

Did this happen when the Ultra-low sulfer diesel appeared in you town? This has been suspect to kill fuel millage.

I'm not sure. How would we know whether the fuel was low sulphur or not? It has happened several times over the last 7 years, and we think we see a gradual deterioration, not an abrupt change. The mechanics explanation is that the PCM "learns bad habits", which is why restoring the original program corrects the problem, or so I'm told.
