People have done it on here. It DOES require the truck to be de-mandated, as the flow is all wrong for the emissions systems to function properly. It also requires custom re-programming of the ecm turbo maps.

Unless you have a specific need for it, it is not recommended .. as it significantly lowers fuel efficiency (about 1 mpg lower is what most people have reported) due to the bigger turbine blades of the 500 series turbo being harder to push around. It also is less responsive by quite a little bit compared the the newer style 400-series that were re-designed for 600+ HP.

Kind of figured all of that. Thanks for the quick reply!
