I just got a 2006 mega cab and i am running a smarty/juice stack on it. I am going to a bigger turbo soon. Can't really make my mind up on what to use. I've used the 66/14 turbos on 6 speed trucks, but I think thats a little much for an automatic. Never tried any of ATS's turbos like the aurora line. Can you guys help me out on this? Thanks
