The manual says 1200 mile break-in period. Personally I will be putting amsoil in at the 1200 mile marker. I'm also worried about Toyota employee's "test driving" the car and not giving it a proper break-in.
He is talking about removing the EGR system. I've done it on every sports car I've owned. Its only there for emission purposes. It helps gas mileage but hurts the environment.
