An aftermarket tune will still not give you 100% WOT but it does correct for overly rich fueling issues in the stock tune and add some additional boost psi throughout the rpm range holding it farther up in the higher rpms. The ford performance tune raises the boost from a max of 20 psi to 24 psi and holds it there longer in the higher revs. The FP tune keeps your 3/36 warranty intact but beware if your car is 2018+ once you flash the FP tune in your car the only way to go back to the stock tune is by having a dealer reflash the "as built" calibration back to PCM for a fee. 15-17 eco owners with FP tune can go from FP to stock on their own at will, that option was removed from the program for 18+.I'm assuming an aftermarket tune corrects for this and that's where the big power gains come from?
An aftermarket tune such as with a Cobb accessport alters the parameters even a bit more than stock and then if you get a pro tune thru the Cobb you can work with pro tuner to get fine tune to what your goals for your car are power wise. There are limits on what a stock block eco motor can handle without severe engine damage occurring. The general consensus is max of 400 HP but that is riding the very edge of reliability, this is what you need to discuss with whomever you choose to do your pro tune.
