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?
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
