Thanks Syn for the info.
My plans for the truck are a 4 inch straight thru exhaust from the turbo back. some sort of programmer or chip. and a larger intake filtering system. I drive a combination of paved and gravel roads roads. but mostly on paved roads. Here in Montana there a lot of gravel. I don't know what type of systems to get.for this truck. I did about the same mods on my 96 F350 and had good luck with it. That one is for sale.
