I would like to have AFM removed but if I do, it appears that GM would disavow the power train warranty. As the only way I know how to do it is through a tune.
Even if the tune ONLY disables the AFM. Even tho that would under the Magnuson-Moss Act I should be able to. So the act doesn't help with that issue, unless I can afford to pay a lawyer and wait a couple of years for resolution. Until/unless that happens GM doesn't have to prove anything!
Not sure the Magnuson-Moss Act really of that much benefit to the average joe.
