Can you post some pics of either the window sticker or the car itself?

That aside..Welcome to the community!

To answer your questions:

1) Removing the plastic engine cover will not harm anything. However, your dealership may ask why it was removed later on being that the car is so new. I would not advise trashing it by any means.

2) With the full list of bolt-ons plus a tune, you will see north of the 300 rwhp mark easily. Just depends on how indepth you go, parts selection and tuner.
