I bought this to bypass the G.M. Active fuel management system. Instead of going to the stealership I purchased this programer to set the computer to the v-8 only setting. This repaired the 4 engine codes I had set on my computer. The Avalanche kept turning off the fuel to four cylinders and setting the check engine light . The engine runs great now and this is a bargain 20 minute repair to program the computer. Ten days now the 5.3 runs like a top and no codes . Thanks Again!
