Power Chip in tow vehicle
Considering putting Econo Mind Diesel Tuner & Banks IQ 2.o in my 2004 Dodge 3500 Dually. Has anyone ever done this and did you get satisfactory results with power and increased mileage?

More power yes but not usually more mileage.
I run an extra 100 HP and my mileage has remained the same. To say more power = more fuel just isn't necessarily accurate. More timing, more pressure, different fuel curve mapping and duration can all result in more power with the same amount of fuel. But usually people use all the extra power so FE gains are negligible.
A perfect example;
my 93 Dodge/Cummins 2WD got 24-25 mpg hiway unloaded (w/LSD fuel). Stock Dyno = 125HP
My 2003 Dodge/Cummins 4WD (much heavier) got 24 (w/LSD fuel) unloaded. Stock dyno = 256 HP.
More efficiency = more power from the same amount of fuel. This is because we only use roughly 20% of the fuel we burn to propel the truck. The rest of the 80% is mostly heat and admissions.
Bottom line is don't count on any significant gains in FE. Also, budget in some trans work so it will hold up to the increased power.
