Was just wondering how other tunes compare to my tunes.Guys/Gals, don't hold your breath on someone posting a "mileage tune". This is a very old thread.
I waited and went with ATP. He set me up with a tune that is so unbelievable that I hand calculated over a course of three months. My results averaged 17.5 mpg in Washington DC traffic and 23 mpg on the highway. These results are hand-calculated as the DIC is off by 1/2 gallon. Research tuners and pay them for their expertise.
