I just purchased a 2002 F250 Lariat Superduty 7.3L Powerstroke 2WD Crew-Cab Long Bed about a month ago that had just been "serviced" according to the used car jockey. It had 83K miles on it, verified with a carfax report (1 previous owner). As soon as I got it home, I changed the oil using a K&N Filter and Shell Rotella 15W40, and changed the fuel filter, which was filthy dirty. I think the used car dealer's idea of "just serviced" means washed up real nice.

Everything works, it looks like new and I have no complaints. Now I want to upgrade a little with longevity, economy and convienience in mind more so than performance. Performance would be a nice by-product.

This is what I am thinking in chronological order. Please tell me what you think:

1. Bypass oil filtration (Amsoil BMK 11 or 12)
2. Diesel Turbo Lifesaver
3. Cat-Back Dual 4" Exaust (Magnaflow?)
4. FIPK (K&N or S&B?)
5. Deep Sump Auto Tranny Pan w/Drain
6. Diff Cover
7. Gauges (Boost, EGT Pyrometer, Diff Temp)

The truck already has a factory tranny temp gauge, but I have no idea how accurate it is. I am not opposed to adding an aftermarket gauge to the pod, based on reccomendations I get from you.

This is my first diesel. I do a lot of heavy towing in hot and humid South Carolina summer weather. So, what do you guys think and what would you do in my position?

Can't speak to your listed mods, but I would review the factory recommended services for the miles and check to see if all of it was done. I just bought a backhoe. Some of the services were never done. Like changing the torque converter and transmission fluid.

Looks like a good order to do things. I have the Diesel Turbo Lifesaver and love it! We did an article on it here at Mrtruck. The only thing I don't see is a chip or programmer. Are you planning to do that too? If so, Edge makes a great one that gives you plenty of power and helped my fuel mileage too. Let us know how it turns out!
