I have a 2018 Yukon XL Denali with the 6.2l. I recently purchased it and am new to the platform. I have read the AFM system is problematic and is best to delete it. There is nothing wrong with the vehicle currently. Can I get one of those tuners that turns it off and call it good? Or do I need to pull out the AFM lifters and associated bits? I would like a hand held tuner that I can plug in, make the changes, and unplug it. I will use the truck for hauling a trailer on road trips, so if the tuner has functionality to improve towing that would be a plus. Thanks for the help all.
