For starters, there is no MAF sensor on these trucks. They are speed density only, and there are 28 separate VE tables that will all need to be tuned. Plus 28 torque tables, 28 inverse torque tables, and 28 ignition timing tables. All of which can be pulled form at any given time, depending on cam positions and torque requests. Get it wrong, and if you're lucky it won't drive well enough to get out of it's on way and torque limiters will prevent you from doing any real damage. Try to force it, and get it wrong, and you'll make a pile of parts out of the fancy $7k transmission.
If you are REALLY comfortable working on LT4 engines with automatic transmissions, and understand how the GM torque logic works, you MIGHT have a solid base to start messing with Ford's control logic. Even then you'd want to start with something a lot simpler, like a S197 Mustang with a 6R80 transmission. You need a good handle on how the HDFX system works, and how to calibrate the system to produce an accurate torque model. Without that, you'll never get it to run right, and you'll destroy the transmission quickly.
A single turbo is not a great idea either, unless you are running a kit that has VERY minimal backpressure. The stock valve springs only have a bout 55 psi of seat pressure, and the exhaust valves will float on as little as 10 psi of backpressure. Even earlier if you don't time the exhaust valve closing point properly. You can go to a stiffer set of springs, up to about 95 psi, but be prepared to work on the VCT phasers control logic to accurately control the cams with the added seat pressure. Again, not a small task.
I've been tuning specifically F150's for the last 6-7 years, and tune the fastest 11-19 truck in the world, and lots of other very fast trucks. 11-14 trucks are fairly simple, and similar to Mustangs, but anything 15+ is a much more advanced tuning process and you need to fully understand the control system to do it safely and successfully. This isn't a fuel/air/spark tune with these trucks, especially considering that Ford never intended them to make this sort of power. So there is very little in the base calibration, especially on the transmission side, that won't have to be addressed. It's definitely not a beginner level tune, in any shape or form.
