I have a 2006 5.9 6speed 4x4 and I want to know what I should do to make it a solid truck. Not a speed machine or a truck that will tow the world if needed. I'm looking to make my truck a all around truck, a little speed, towing ability and fuel. I have a S&B cold air intake, 5" turbo back, and a smarty Jr.. What else could I do?

 

nothing!

 

gauges. EGT, boost, rail pressure, and fuel pressure. good lift pump like airdog or fass 150, and overfill the transmission by 1QT with synchromesh

128:1 2 stroke mix with the fuel will help improve fuel economy and lubrication to the fuel to help protect your CP3 pump and injector tips from premature failure.

2-stroke is not needed though if you run B5 biodiesel anything 2% soy based biodiesel or higher has excellent lubrication properties over standard petro diesel.
