So I have a 2002 f150 5.4l with 315/70/17 and I just wondering what options would be the best through the programmer to get maximum milage.
Fyi I will be getting 33 most likely aftr taxes

 

No advice at all?

 

Are you saying you already have a Superchips Flashpaq? If so, then you should have noticed there is a tune in the programmer called Mileage XS Save. That is the tune I run in mine and it bumped my mileage up about 1.5 mpg. I drive about 60/40 Highway/City and I get about 13.5-14.5 driving somewhat aggressively. However, I am running stock sized 265/70/17 Goodyear Wrangler AT/S's, unlike you.

Hope this helps. Let me know if you have anymore questions.

 

Could I change the tire size in the programmer and wait and when I get 33s program it for that

 

Yes, the programmer has the option to change the tire size.

 

Ill try tgat I got half tank so we will see from there
