Hey everyone which chip/programmer is best for fuel economy??

 

Dunno man. I'm running a DiabloSport Predator and got 23.5 driving like a grandma. Normally I'm right at 20. The price was right on the Predator, but if I had to do it again, I'd go with the Smarty. One thing I've learned building this truck is that the customer service of the company you're buying parts from should be high on your list of priorities. Diablosport has the worst friggin customer support I've ever seen. I doubt I need to tell you about the reputation Bob and Marco have built with the Smarty.

 

Believe me or not, I am just throwing this up there for you to ponder, but I have been running a mix of Power service and Opti Lube in my truck. For fun I filled up ( Topped off) my tank when I had used a quarter of a tank and I went 207 miles on 7.7 gallons. Previously I could only go 140-160 miles on that same amount of fuel.

 

I bought the Painless Stricker Module and realized a .01 increase in mileage. Yea, .01. My mileage towing went from 10.84 to 10.85. I did get a free sample of a LubeGaurd product that went in the oil and it did help my mileage, problem is I needed 3 bottles of it. Not really cost effective.

 

i have the smarty jr the 04.5 through 07 are the hardest to remove all of the damage we started our mods for better fuel mileage a year ago we should have most of them installed by next month we are going to use a mp-8 to get the rest of the timing we want and to increase rail press, a pdr cam and a ads 3000 turbo it seems most of the knowledgeable people we talked to have more experience in efficiency power and not towing mpg we finally found a Cummins engineer that showed us each thing they did for emissions , some like the cam and turbo are expensive but we have figured out a solution for all but one of them we need some one like smarty or tsp to move the 3rd injection pulse closer to to the 2nd

 

the x2 and proper inflated tires and an intsake with no muffler,
