After using the AFM disable device on my 2007 Suburban LTZ, I have more power and acceleration i.e. better road performance on the hilly roads around Austin, Texas area. Equally, I am pleased with the reduced oil consumption I have achieved by staying in V8 mode all the time (no cycling back and forth to V4 mode). Was using about 1 Qt of oil/1,000 mi, now am using 1 Qt oil/2,800 mi. Thanks for the improvement.
