Re: 06 silverado/ hp increases?
it won't really matter, because you can always hook up the programmer after you install the intake to make the modification. Make sure you store your factory settings, because if you have to take it back to the dealer for servicing, it will void the warrenty. You will want to load the defaults before you take it in.
