New guy lots of questions

[Gegizi]

I have a 2005 ford 250 6.0 with aBanks Ecno tuner,air box,and Inter cooler. I have had many problem from over heating, head gaskets, turbo sticking turbo modulator sticking. Boot blowing off of turbo discharge, to now the FIMC. I have had this truck in many ford dealers since I have owned it. Ford has been great ad has address all my issues.
I purchased an extended warranty when I bought it and purchased an other when it expired; it has been worth every penny.
How will programming my FICM work with what I have. I get about 14-15 mpg normal driving and about 9 -10 mpg towing 1200 lb 5 er.
