I recently just purchased a new black Z06 i was wondering i only have 1000km on the car, from the factory do they put some sort of restriction in the computer until it is fully broken in. Basically what i mean is, does the car have its full power right from the get go! or do they de fuel it when you get on it for the break in period. Thanks guys!

 

no restrictions whatsoever...however, your car won't make full power usually up until 5,000+ miles.

 

I saw your original post, neverendn, and thought I replied. Tailwag is correct as far as I know. Among manufacturers of non-exotics, only BMW uses a computer limitation on new engines or hard throttle. Some of their M models limit power whenever: a) the engine is new, for the first 3K km, etc., b) whenever the engine is cold, they will refuse to rev over 3500 RPM.

As noted, your engine will produce a bit more power as it wears in. Typically, however, factory engines are so well machined that they are "half worn in" anymore straight out of the box, so the increase is quite small: I would expect if you dynoed the car new (say 200 miles) and then at 4000 miles, you'd see perhaps 10-12 HP increase as it wears in and friction is reduced. The difference is much greater on engines you have built up modified or custom, because even the best machine shops cannot match the tolerances the factory achieves on cylinder walls, etc.: my C5R gained 30 HP between 800 and 5000 miles.

If the car feels "slow" to you, remember, first, that cars with fat torque curves often feel much slower than they are (see my post a week ago of so under General Tech). Second, remember that any car feels much slower from the driver's seat. Have a friend take you for a ride in your car with you in the passenger seat: it will feel like it gained 100 HP.

 

There are no restrictions within the actual computer or engine, but I'm pretty sure they have some restrictions/recommendations of how you drive the car for the first 1000 miles or so.
