Here's a nifty holiday gift idea: our good amigos at American Expedition Vehicles, creators of our one-of-a-kind, crazy-mad Teal Brute TJ project, have a way-cool control module on the market for new Jeep Wrangler JKs. Called the Pro Cal, it's a plug-in solution for wheelers who need to recalibrate their vehicle's ECU to accommodate for changes in tire size, engine idle speed (i.e., for winching) , and even reduced (aired-down) tire pressures that'll work with your rig's newfangled pressure monitoring system. The module's a plug-and-setup, it'll only set you back $129, and you can find out more about it right here.
