Welcome to fordtough.ca! I'm no expert, but start simple and maybe replace the fuel filter.
Another thing I've has personal experience with is a little bit of water in the gas, throw in a bottle of gas line antifreeze and see if that helps any, could be a crappy tank of gas.
Its not for everyone, (check the owners manual to see if your trucks computer is tuned for it), but personally, I've had two 6.2L engines, and both have run better on premium.
But then, the Raptor is tuned for premium, if you're not tuned for premium, its a waste of money.
Good luck and welcome, I lived in Peterborough for 8 months while I was going to Trent University, beautiful little spot.
