***"The product information says it DOES NOT drain the battery**** this is very important!!!!

Be CAUTIOUS Most of the AFM disablers do drain your battery! You have to unplug them every time you get out of your vehicle or you will be stranded with a dead battery. I bought this for my 2008 Chevy Silverado but a friend of mine had a tuner which I didn't knowhe had,  when I bought it and he tuned it for me. This has not been used it has not even been open it still sealed in the box.
