Not scams, just the factory boys can't afford to leave much untapped power on the factory floor these days.
Even twenty horsepower extra will likely only be at the very top end, hardly ever useable.
Supercharged engines are another matter entirely. The factory tunes these for reliability and possible misfuelling with inadequate octane. Aftermarket and even the factory boys have no trouble "finding" extra useable power and torque by over boosting.
If you want more power from your XF just trade it in for a supercharged one. Those can be tuned until your underwear needs replacing.

The price difference includes a lot of extras to deal with the additional power. Bigger brakes, wheels, tighter suspension with electronic adjustment, better seats and so on.
The price difference drops as the cars age.
My point is only that Jaguar beat us all to it. If you want to chop a second or more off the 0-60 time trade up to a supercharged XFR or SCV8 it's cheaper in the long run!
