My dad's 7.3

[Schmidty]

My dad asked me about gaining mileage on his 2001 7.3 Ford diesel. I own a dodge, so I figured I would ask some ford experts.

My dad is a dairy farmer and quite practical. The question is simple; my dad only cares about gaining mileage (real mileage, not potential mileage gains), not power.

He wants a simple chip/programmer, and nothing will be changed on the truck (everything will remain stock). There will be no exhaust mods, etc...

Thanks for your help,

Schmidt

Well, the problem with using a tuner or chip is you really need gauges to monitor everything especially if he is using it for towing. As far as I know the highest HP settings give you the best MPG gains as long as you keep your foot out of it

def. have to have gauges.

gauges and exhaust+intake are a must to get air flowing

get some smaller tires. usually trucks come with a few sizes depending on the model and options. Mine came with 265 my buddys came with 245s. Same truck same year.
Change the air filter, run synthetic fluids and stay off the throttle driving like grandma.

I wouldnt put a chip on without any of this stuff

If your dad isn't willing to do other mods he should just keep his truck tires aired up!!! Before you add more ponies to a diesel you need to add gauges, and a better flowing intake and exhaust. This isn't a Ford thing it is the same with all diesels. It is the difference between doing it right or doing it wrong, plain and simple!!

I agreee, there are supporting mods needed to run a chip correctly

Absolute must. No b.s.

At the bare minimum get a EGT gauge, straight pipe the exhasut and add a DIY intake.
Adding power without these can result in failures
