Review on Range Technology Active Management Disabler by Greg Anderson

My 157,000 mile 2011 Silverado has recently had the Service Selectrak and Service Traction Control warnings and a blinking check engine light. Last Friday night he started stagnating and stuttering. I googled the problem and found AFM Disabler. I ordered it and it arrived today. I literally just plugged it into the OBD2 socket and started the truck and the problems are gone! I rode 20 miles and it was smoother than it's been in a long time! I recommend GM truck owners to try this before making another costly repair or swap!
