Looking for the best programmer for fuel mileage!

[BBowers]

Well i have a triple dog by bully dog programmer, maybe picked up 1to 1. 5 mpg maybe. Not great, but lots of power! I have a 2005 3500 drw 4x4. Bullydog wants to sell me a propane kit says it gives 3-4mpg increase. And it only takes 1 gal of propane to 6 gal of diesel. So they say. I say u start burning propane too!! I Don't see why this truck can't get 20-22mpg on flat ground no load and 60-65 mph. It has so much torque at low rpm it should get awesome economy. I am getting 15 to 17 with 18K miles! I want to find a better programmer if there is one. Will a rokktech sensor work with with my triple dog?will it give me more mileage with the two combined?HELP!

All the additonal injection events on the common rail motors are part the reason why the fuel mileage is sometimes lower. They throw multiple shots to reduce emissions.



I average around 19. 5 with my current set up.

Your not going to find much more with 4:10's. Look into an auxilary gear box for a taller cog. Their not cheap.

I got around 18. 5-19 with my 03 4x4 quad cab dually with just a TST module. That was a 6 speed truck

BBowers,



Propane will do that for you, but you must drive with MPG in mind to get it as propane makes HP too and it's pretty hard to keep your foot out of it etc. Check out the MSD propane kits we have found them to have the best safety features and best MPG gains, they have their own ECM to control the propane flow and lots of other features too.
