If you are planning on installing/performing significant car/engine upgrades, should have them done as soon as you get the car (when the car is brand new), wait until the break-in period is over, or wait after the car has some good mileage?

I would think that you'd want to atlease wait till breakin as you'd not be able to exploit them until you can open the beast up, the only exception is if you're swapping the engine out!
