Please Help

Need to do something with my work truck. Drive 100 miles a day and want more power, but more importantly, better fuel economy. I have cold air intake and straing pipe exhaust. Everything else is stock. Its a 2001 7.3 auto trans with 140,000. Everything I have read has confused and taken me in tons of diffrent directions. The two items I keep hearing is the DP Tuner and the TW chip or tuner. Please give me yall's input. Thanks

If you want More Power, that's gonna be using MORE Fuel to make it...

If you want Better Mileage, DO NOT SPEND ANY $$$ for it, drive it differently (like it had even Less Power) and you'll see an increase (I get 14 driving it like a Guy, 17 like an Old Lady) You're choice But WHATEVER you do, don't let anybody fool you into thinking they have a $400 chip that's gonna "Pay for itself" anytime soon. Those guys just want Your Money!

Budget matters too. But like he said you'll spend hundreds to gain 1-2mpg.

The basics:

Air pressure in tires.
Synthetic fluids especially in diff's.
Maintenance like your brakes and such.
Check for boost leaks, google "boost leak detector 7.3 powerstroke" a small leak can cause a dramatic drop in MPG.

If you want to spend money. Get single stage injectors and some kind of tuner. I recommend DP as they are who I've delt with and they will work with you if you have issues.

You don't mention the mpg you are currentt getting?

What truck? 350, 450, 550? What gears in the diff? Lift, bigger tires? What weight on the truck?

These guys aren't kidding. The best mileage I ever got was before I started modding it.

If you want economy, keep it light, keep it low, drive like a granny.

I respectfully disagree with most of the above. I do agree that driving habits are the biggest player in mileage. Running the 65hp Economy PHP tune, I went from 14.7 to 18.2 mpg on the freeway with no other changes (still used cruise on the freeway @ 70mpg). Put in chip, BAM! better mileage. To say that you can't gain mpg with a chip is just uninformed. The biggest problem with chips is that they make the trucks fun to drive and you find yourself playing with the throttle a lot more than you need to.

Good to hear Macon, looking at getting the PHP 6 position but wanting to hear more of what your saying. Do you track your fuel economy on fuelly.com? I do and drive a lot of miles, it will be easy to see if the chip really helps if I get one. In fact I would be the best advertisement PHP could have.

I love having tunes and mods. Just be aware that some people see more of a jump in mpg than others do.

Absolute truth. Every truck acts just as different as the nut behind the wheel. I got before and after at the pump over several tanks of highway only driving (summer fuel). From Macon, GA to Panama City, FL, I got 20.0 mpg, but very little of that was freeway. Most was <65mph. Winter fuel has my numbers pretty low, but I've been mostly city driving as well. Last fill up was 11.something. Winter fuel, plus horrible driving habits, so I can't complain too much.
