What's the best gas mileage improving programmer for my Dodge 2500 Cummins 5.9 truck?

 

EFI Live Tuned Correctly

 

EFI LIVE from a reputable tuner.

 

Smarty if your not rich!

 

Don't think your going to go very far at all by putting gas in a diesel engine.

 

If you have an 06 to 07, or 07.5 to 09 ( I think ) then EFI Live is the way to go.

as for price, I didnt shop around but I saw smarty sr was running 685 from alligator performance. Efi Live from Anarchy was less than that for me. Definitely worth looking into. my .02

 

Another vote for EFI Live. We offer custom EFI tuning in house. I have been tuning with it since 2008.

 

If you haven't gotten tuned yet, call Innovative Diesel great guys.
