:s:what needs to be done needs exhaust front to back any thoughts steering stabalizer what should I be checking or modifying just looking for good strong truck that can tow my boat around want it to sound good not to loud mod chips tranny filter systems gauges where to buy etc. looking to learn

First off get a fuel pressure gauge and an aftermarket lift pump either AirDog or Fass. Then if you are going to add a module or programmer you need to tear into the tranny and put at least a new TC and VB. Exhaust you can go with an expandit kit if you go to the quote thread and ask our vendors here on DB you will get some good prices. Also I would install a new air intake as well.
