Just picked up a 2007 Yukon to replace my 2001 Yukon. Been reading about AFM and its pros and cons. My question is this truck has run perfectly for 150K with 100% factory setting. After reading some of the posts part of me is thinking I need to delete AFM ASAP. The other part thinks its worked perfectly for 150K and “if it aint broke don’t fix it”.
Opinions appreciated.
