All my vehicles are modified yet I have not added anything to make more power. (arguable, I did an intercooler on my 3.5 ecoboost f150 to reduce temps while towing not to make power)

Modern cars are plenty powerful, you'll get more out of tires, brakes, and suspension than 10hp from an arguably legal bolt on power adder.

In my field (diesel) we were making 100hp over stock just in a calibration change. But yes, some modern vehicles make more than double the torque over what they did a little over a decade ago.
