Default Better fuel mileage in a 96 ford 7.3

I picked up one of our old shop trucks to use as an everyday beater/tow rig. It is a 1996 4 wheel drive f250 with the non-intercooled 7.3 powerstroke. It has 200k on it and is in bone stock rusty form. I would like to get what I can out of it for fuel mileage and not put too Much extra strain on the old girl. I was thinking chop the cat off and getting a small programmer for it. What are your thoughts? I have never owned a diesel for a personal truck, just a company owned work truck so I am pretty clueless.

Intake exhaust and programmer. If you really want to then intercool it from a newer 7.3. Id reccomend tony wildman, dp tuner or bill at php. Gauges would be a good thing, keep the pyro and boost as low as possible and you will see decent mileage.

with the Banks exhaust kit I ordered it removed the muffler but left the cat in place, couldnt hardly tell the difference in sound. If you are like me and dont want to pollute then leave the cat on. In Canada we have to pass smog tests every 2 years . I didnt have much trust in any diesel programers except Banks

I know it's a different beast but in my '00 4x4 eclb powerstroke I just have some sort of CAI, 4" downpipe to straight exhaust, and a DP tuner. It woke the truck up quite a bit and I usually pull 17mpg in town and around 20 on the freeway. I don't drive it too hard which is the biggest factor in these trucks. With the race tune and getting on it the mileage can drop off pretty quick. I have not tracked my 96 powerstroke yet but it is still stock. I'm hoping with simmilar mods it should do better as it's only a reg cab 2 wheel drive.

I don't want to dump a bunch of money into the thing. I am looking for things I can do on the cheap to help my mileage out. I'm not looking for performance, Hell the thing already outpulls my 04 superduty work truck with a 6.0. The thing is a bare bones rust bucket that is butt ass ugly. It's not worth dumping alot of money into.

Buy just the down pipe. Mine from mbrp was cheap. Then a straight section of 4" pipe and get a older fseries diesel tailpipe from dyno max.

I tried a cold air intake and seen no difference. No other mods to motor other then boost and egt gauges

Look up powerstroke.org theres a bb mod. Put a bb behind the regulator spring, they give good instructions on diy intake parts.

Let me know, I may be interested.

This is why I don't want to put too much into it

As far as tuner I am very happy with my DP I bought it from a member on here and sent it to Jody to flash it for my pcm and tuned for my supporting mods. He called to verify everything before it was sent out as well, great customer service. I don't have experience with the larger brands (banks and Edge) but have heard for the 7.3 the best are Tony Wildman and Jody Tipton. Like masterbeatty said gauges are important you definitely want a pyro as well as trans temp (should have this regardless if you have an auto).

You are right, I really should do gauges. I'll check out those programmers also.

Sweet, thanks. I'm in no hurry to do it since all my time has been going into getting my barn setup. Exhaust and a programmer is easy and quick and I can do that anytime but an intercooler would probably wait til late winter-spring.

Just did some looking and people seemed to suggest doing the blue spring over the bb. I don't know how much a blue spring is but it can't be that much.

In my opinion i think the banks, superchip, bullydog are a waste on the 7.3. The edge is nice especially if you go with the cs or cts. You get the programmer plus gauges all in one. You can set warnings and all the fun stuff. But as far as performance goes the custom chips are nice. If down the road you swap over to 99+ injectors, hpop,intercooler and turbo they can tune the chip to run the injectors. Yours are single shot injectors with a 15degree hpop. The superdootus run split shots that flow more and they run a 17 degree hpop.

I believe they are from the 6.0. It is supposed to bring your fuel pressure back to what it should be. The bb does the same thing just more dicking around.

Just stopped by and got a price on an exhaust kit. All stainless 4" with no muffler or cat and that includes a 4" down pipe for $309. Does this sound like a descent plan for the ol' rust bucket?
