I haven't spent to much time looking into fuel management tuners, but I would like to know more from you guys that have them. I have a stock 2010 Titan cc 4x4 SE. I absolutely love this truck. I've had plenty of trucks but this one is a keeper for sure. Now I didn't buy this rig to save gas, but up here in Nor-Cal reg gas is $4.35 a gal, and going up. I would like to get a tuner for both HP if needed, and right now maybe a tad better gas mileage. Can ya help me out with some real world experience and recommend which tuner would work the best on a stock rig. Thanks a bunch.
