That is not true, and even TFA points at why that can't be true: to your insurance, to vehicle taxes, etc. you declare the power _of the installed engine_, not of whatever software interlocks you, your tax advisor, or the manufacturer have decided to install on it.
TFA already says the car is registered at the maximum power level regardless of the actual software cap. So you are _quite literally_ paying for it, at least in terms of increased insurance and taxes.
