In Short, just say no to Banks. Way over priced for what they give you in return.

First, you want to get 2 micron filtration going as quick as possible. Our High Pressure Common Rail Engines do NOT like dirty fuel. Cummins says that 2 micron filtration is ideal, but Dodge put an 8 micron setup on our trucks. How does our engines repay us for not having 2 micron filtration? By killing $350 a piece injectors one by one... I just had to replace all 6, and that hurt a lot.

Depending on what you are wanting to do with the truck, Transmission Upgrade and Guages are next. The trans in our auto trucks is the single handedly biggest flop Dodge built into these trucks. The 48RE is a great trans after a good Torque Converter and Valve Body is added, but a few more smaller items need to be done inside as well.

Next would be an auxilary fuel pump. Something like a FASS, Walbro Setup, Air Dog or whatever. The stock fuel pump, will not keep up very long once you start turning the power up any.

Then after you now have the supporting mods, you can add some performance, in the form of programming. My vote goes to SMARTY. I run it, and it is a smooth power adder. Go ahead and get the full SMARTY, not the Jr. If you dont want to run high horsepower, then run it on the lower settings, but if you decide that you do want more power, instead of buying another programmer later on, just turn the SMARTY on up, and you have what you need.

I would say:

1. Good oil/fuel filters
2. intake
3. lift pump
4. Safe electronics (smarty jr, etc...)
5. valve body, torque converter
6. Bigger electronics (smarty sr, etc...)
7. Injectors
8. Head studs
9. Turbo

Depends on how much you want to spend.

Glacier Diesel Power has a stand alone 2 micron filter setup that costs about $100, and from then on you can buy filters for around $17 a piece. I have that setup on my truck, and I left the stock filter in for additional purposes, and also for the water seperator.

Other systems out there have the fuel filter and water seperator on them as well as act as aa fuel pump, but you will be looking to spend around $500 for one of them.
