Have a 2010 Silverado 1500 Z71, 5.3L. I am putting on some 33" inch tires with Rough Country 2" Spacer this week. I also tow a Mastercraft X-Star wakeboarding boat. My truck got a "horrible" 7.2 mpg on my last trip out of town.
What programmers do you guys recommend with the larger tire and towing of my boat/16ft trailer with atvs?
