> Little smoke on start up, black smoke when WOP when on performance, more on extreme. Just did the fuel filter with oil change, haven’t tested mileage since. This is the first tank since I got it. Tires are 315’s. It has a 6inch lift, it does need an alignment. And I just remembered it pulls to the left when I brake.

Well that smoke/soot is unburnt fuel. Any od the performance tunes will decrease economy. Also larger tires with no speedo recal will off set milage calculations.
