Stay away from the banks stuff. LONG before you add power to your engine, you need to add the proper gauges. The easiest/cheapest alternative is the addition of an electronic gauge set such as the edge cs or cts. You really need to know/watch your engine oil temperature and you rcoolant temp to determine of your oil cooler is plugging up. If it does, the egr cooler could fail. If that happens and is either ignored or is un-noticed, you will notice whne the head gaskets pop. For the cheap price for an electronic monitoring system, it is WELL worth it.
Here is the test to do to check your oil cooler:
Get your unloaded truck up to normal operating temps (coolant temp 190° +/- a few degrees). Once that is done, find a long flat section of highway. Set your cruise control for 55-65 MPH. After a few minutes, start watching your oil temp in relation to your coolant temp. If the temperature differential (known as a delta) exceeds 15°F, it is time to replace the oil cooler and the egr cooler (or delete it if you can).
You should also be monitoring your fuel pressure, and this will require the addition of a sensor for this, since there is no stock sensor for this. The reason for that is that should you fall below 45 psi, under any condition, you are replacing your injectors.
Next, before adding power, you want to know what your exhaust gas temps are. This will also need to be an additional gauge with its own sensor. You don't want to heat your turbo beyond 1300°F for very long, unless your plan is to replace it.
There are other parts that should be upgraded as well. Two of those parts are redesigned by Ford to deliver and remove oil quickly and without restriction to your turbo. The updated oil supply line and the updated oil drain line.
Another mod you might be interested in is known as the "zoodad" mod. This is an easy mod and will deliver a colder air charge. All it is is you cut a hole in the front support directly in front of the stock air intake snorkel. You DO NOT NEED to do anything to your intake system. No "elbow" no "cold air intake." Your stock air cleaner and air intake system supports up to 500 horsepower without an issue.
Once all of the above is done, then you can start looking for an SCT X3 and getting a custom written tune specific to your truck. Gearhead, Quick trick automotive and Innovative diesel are the top three, in no particular order.
