Adding a pair of turbos and picking up 150 whp makes you giggle every time you hit the gas, and scares you a little bit.

It takes a lot longer to feel like you need more power when you add 150 whp than when you add 10. It does happen eventually, but that's true for anything. Unless you drive to work in a F1 car, everything you drive every day will eventually feel slow. The only way around that is to buy an actual slow car for a daily driver.
