I am considering adding the system to my LLY. What I am looking for is just a bit more performance and a little better fuel economy with it, not a race truck. Based on the posts I have read on the subject, I believe 2 or 3 is as high as I would ever dial up since I want to keep the truck stock. Will I be happy or sad if I add it?


I love this forum. I have learned a great deal. Thanks to all who post here!
