Question about DP Tuner Economy

[JoeyCleland]

Hi yall,
Got a quick question. I want to buy a DP tuner for my 2000 f350 6spd, but can really only afford the chip, Switch, and 1 performance file. I routinely drive 800+ miles unloaded. I hear the 80hp econo is good for the automatics, but what about the mileage gains with the handshaker? What kind of mileage are you getting with the 120 race program? It is the one I really want but dont want my mileage to suffer.

Thanks a ton

Joey

a lot of people have had better luck with the higher HP tunes... but that is if they can keep their foot out of it

I don't have any experience with this personally though

[JoeyCleland]

cmon guys I know one of you out there has the answer to this???

From how I understand it, The economy setting just changes the shift point's of the auto tranny.

I'm not sure it does much more that that, for econ. The key is just keeping your foot of the go pedal.

[JoeyCleland]

So now the question is if I drive with a light foot, which will get better mileage, the 80hp or the 120hp and by how much?

[jfines@cox.net]

I think for that question I would give Tony Wildman a call. He helped me out and I had him reprogram my chip.

i don't about the PSD but i do know that on my duramax with a higher tune(200hp rated at the crank)i increased my fuel economy by 4mpg verses a 40hp tune but you gotta keep the Throttle Postion Sensor in check..

I'm no tuner either but it is my understanding that the higher hp tunes increase the timing which is significant to mpg so if you keep your foot out of it you will see better mpg on the higher hp tunes.

I don't think you will see a significant difference one way or the other while just rollin' down the highway. But as mentioned if you do bum it up, and your foot is feeling heavy, you MPG's will probably drop a bit.

The only thing I have found that made a difference, and it's a small one in MPG's was the 18k mod, or 10K mod, may just be though, someone else could chime in with what they have experienced with it.

Good luck keeping your foot out of it. I can still get 18 mpg on the interstate with my dp tuner set on 80 econo. When it comes to the throttle, my will power isn't very strong.
