Need Increase in fuel mileage
 

Truck is a 2000 with the 6.0, looking for a ''chip'' or "programmer" what ever its called for better fuel mileage. Do I need to send the pcm in to have it done? Or can I get one that I do myself? What is the average mpg increase if you drive normal?

Thanks!

No chip or tuner. Contact Justin at blackbearperformance and tell him you want a economy tune for mpg. Usually a 2-3 mpg increase

you should be able to find a tuner for pretty much anything obdII but I haven't done much in that area
