Usable power for the street?

The level of power I want is as much as possible without it becoming NEEDY. I control what the car does. Drive a 390 hp car on a 6” tire on the street you need to pay ATTENTION. Painted lines, small crests in the road, sand. All things that can bite you, however the more I run the car at the track the less spirited driving I do on the street. Nothing to prove on the street, there is always someone quicker. So basically blip here, blip there, always going straight and putting around.
