well ficm tuning has been out some time now, just curious if anyone has seen any actual mileage improvements? Specifically if you had the factory vxcf4 base engine calibration. (your truck would have non inductive heating factory ficm cal of say AMZ2AL12).
I don't need inductive heating, but I do need better mileage, lol.
Thanks for any info.
