Welcome, thanks for joining!
Start reading up on the fuel system on this car, you can't do "normal" things on the ecoboost and the only stand alone I know that would work is the Motek for $10K and that would cause a TON of headaches.
I sell an aux fuel system that is a piggyback with stock fuel system, you could use the micro/megasquirt setup to control that but only the 6 aux injectors.
Nitrous works awesome on the motor in my experience but make sure not to engage too low of an RPM with anything over a 50 shot as you'll spool up the turbos and cause fueling issues with the stock setup.
Make sure you do lots of testing/tuning on the dyno first!
Have fun!
