My 2005 Explorer ( 4.0L auto AWD, standard gear ratio XLT) is getting in the mid 13's in mpg. My 98 with a 4.0L same trans got mid 16 in town, and 20-21 on the highway. What is the deal, and does anyone know a good tuner in North NJ who can fix the computer? I talked to someone at a place in Freehold, i think it was HPE, that I found on my Corvette site, and they assured me that they could fix it with 3-4 mpg better. What do you folks have to say?
