Just got a 06 lly has 160K miles I want to put a edge system on it. Will it hurt the truck or to old to start now? Man I love this truck gets better mpg then my 03 v6 s10 I don't understand it but it does .
Make sure the Edge system is not an old unit. The old ones had issues. Shouldn't hurt the truck as long as you install the EGT probe and not tow above level 2, if not stock power.
It is a very easy plug and play however you still have to drill your exhaust for the exhaust probe. However if the truck had it before you may already have a hole tapped in the manifold.
But it could also have just came with a sticker...
