Tunes
 

I have a 01 psd and was curious to see if there is much mileage difference between the 65-80 daily driver programs? I am thinking of getting the following tunes.
1 stock
2 80 daily
3 80 light tow
4 100 performance
5 high idle 1k
6??? fuel sipper? whisper mode?

I ran a dp tuner on my last 7.3 so I have had some experience with "custom" tunes. I tow alot on the weekend but I am only pulling 3000 lbs. Is 80 tow the best option for mileage when towing?

thanks,

Bill
