I have an 04.5 3/4 ton that is stock. I would like to put an Edge Juice with Attitude in it. My question to the pro's is "if I stay on level 1 2 or 3 and dont ride it hard all the time, will I tear anything up? If so what would it be?

 

You shouldnt hurt anything running on 2-3, Ive ran mine on 4 as well for about a month and really saw no difference in fuel mileage between 3 and 4.
Like anything, if you rag on your truck you can break something, but just having a little more power shouldnt hurt anything as long as you dont lay into the skinny pedal all the time
