Good thoughts on the AMP. They have a Platinum in Red, but man...that thing needs a debadge fiercely, and I would have to figure out if I could get that big ass metal plate off the tail gate that says P L A T I N U M. It is ridiculous.
Brian, the cold start does not appear to be an issue with this engine. Our company owns over 20 2012-13 F450s, and I was in Prudhoe Bay last week where one of my customers leased a fleet of 80 F350s so I got to ask him about extreme cold performance. He states that the GM and Ford both start excellent without being plugged in IF they have 5w40 or 5w30 Synthetic
