    2013 Buick Regal GS

    Hello, just installed a k&n cai on this car and i'm having issues with the car throwing lean codes and bogging on full throttle. If anyone has a tune file for this car or can tell me what to adjust I would greatly appreciate it. Thanks.

    Usually you have to re-calibrate (re-scale) the Mass Air Flow sensor calibration, .. according to the fuel trims.
