I agree with both above: springs and plate. I'd probably do the springs first because they really will give your truck a kick and they're not much money at about $150. You can get a #8 (230hp, 605 ftlbs) plate on ebay for $75. usually, but it's a TST development so you'd probably be stepping on some good people's toes by buying a cheap questionably made and hardened copy. TST includes a boost elbow and a full set of instructions with even with a video tape to guide you through the installation. I doubt that with the ebay seller you get that or the refund guarantee with trade in rights that TST will give you.
