I just finished Mega-engr’s California Style deletes of the DPF & EGR. I have the Smarty S67ME and wonder what would be the best program for fuel economy? MPG's are the main reason I wanted to do this. I don't "need" allot of extra power. Right now I have program #3 installed.

 

With the auto, the best reported mileage is on SW#3. I noticed it to be the best for me. I ran SW5 for a while but I think SW3 gained me about 0.5 MPG over SW5.

 

Thanks for the input!
