Let me start off by saying the FJ is the greatest vehicle I've ever owned. That being said the gas mileage is terrible. My summer truck is an F100 with a 360 and I can still get 20 miles per gallon fairly regularly. Has anyone looked into a temporary chip or mod or something to get better gas mileage? I would love to have this as my daily driver but I don't need the balls out torque that it puts out all the time, just when I want it.
