Does anyone know how to make my truck get more than 11 miles to the gallon highway? Quick background on my truck. CC only have 3700 on her right now, 7" CST, Stillen exhaust, Brute Force CAI, Bil rear shocks, DR's up front. I have read on here that folks flash their trucks computer. Which flash should I use. By flash I mean the multi. accelerater touches and releases when you add mods. thanks in advance
Help Requested!
