Bought this to disable the AFM on a 2007 suburban, easy to use even if you are not too technical. Worked great, installed the 87 octane tune and modified to disable DOD (AFM). Also firmed up trans shifts and took the top speed limiter off. If you are lookinjg to disable your AFM this does it easily!
