    Can this disable active fuel management AFM (v4 mode)? If not what tuner can for a 2017.


    2017 GMC Sierra v8 2 wd ,the six speed transmission acts like it's not sure what gear to go into sometimes and definitely has pedal lag will the sct programmer fix these issues also can it be programmed back to normal for warranty issues. Thank you,


    I need my truck to stop switching from V8 too V4, will this programmer preform this function? Thank you Ricky Gomes


    As you are probably aware of the transmission shutters at times and also at low speeds idling along vibrates as if not sure what gear it should be in. Will this tuner help those problems? My Sierra is a crew cab. Thanks for any help, Brian
