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?
