bahahaha! Man you will love the tune. I took all of mine out and I believe it has been on there for almost 40000 miles. Truck has 145000 now. Nothing has happened to mine so far and I literally beat the hell out of it up until about 3000 miles ago(knock on wood). I literally probably went WoT everytime I got in the truck. Mine will chirp 1-2 once in a blue moon. If you're spinning, you aint winnin though! (Not saying I'm fast lol.) It is fast enough for now. I love it. Spot on Mail Order. Have fun. 100% removed!
