I currently have an 01' CTD and I am considering getting a new truck, possibly the Mega Cab. Question is... ... . am I better off getting an 06' or waiting for 07'? I hear there may be some changes in smog regulations for diesels in 07', and if that is the case I am assuming that I want an 06'. I don't follow threads on the Gen 3's very much seeing as I have a Gen 2, so what otehr things should I know? I already plan on doing transmission upgrades, injectors, box, turbo, etc to get up to 500hp and a KORE kit, but want to know if there is anything else to be aware of.
