Hello everyone. I am obviously new to this website and would like some help. I have a '02 Duramax/Allison and I am looking to improve my mpg. Right now I am getting 16.5 combined city/highway and 18 straight highway.
I would like to buy a programmer, and I am more concerned with getting better mileage than anything. Is there a programmer that yall would recommend to improve my mpg?
Thanks for your help.
