Welcome to the Org.
Your gonna need to be educated in the 6.0.
Send the Banks back. The first and most important mod to do will be a gauge/monitor system. There maybe some hidden issues with your motor that need to be addressed. A good monitor solution will save you money and headache.
I'm gonna give you links to read, these will start you out on getting to know your 6.0 and some common issues.
This first link will point out some of the issues with the 6.0, open and read all the info. When you get to the "coffee table" books, start with the 2003.5 6.0 and work your way thru all the 6.0 years (lots of info).
This next link will get you started with what should be addressed after you have a monitor solution. You need to check the health of your motor.
