Looking to try a tuner. I've heard about the EFI live improving fuel mileage and power. How much does it realitically improve mileage pulling and empty? Also is there a way to have someone program it for cheaper than buying the $500 plus dollar system?

I'm sure some vendors have some dsp2 tunes they will put on your truck...... Go redo the post in the vendor price request or call some of them.....

efi live is bar none the best tunner for ur dmax. the only thing is that u need some one that knows what there doing to instal. u can adjust any thing on the dmax with efi live but if u dont know what ur doing u can also adjust things wrong. so do some research and u will be impressed. they can tune for power and millage
