The Turbos are BD-Powers twin set up. Transmission is BD auto also.
There was another 05 Dodge there 6 speed which had BD's bigger twins on it and it layed down 700+ hp on diesel only with very little smoke. It was very impressive. I think it has dual cp3 and F1 Flux 3 injectors. I know it was running a Smarty stacked with a pressure box.
