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.

Good information. Thank you very much.

My numbers are hand calculated, and my tires are stock. This would be the first time I did anything to my truck.

What sites do you recommend using for finding good deals on programmers? The best I have found so far is on Lagunaspeed.com

On another note. I went for a ride in a friends stock '07 Duramax yesterday. Wow, that is a fast truck.
