If you plan on keeping the car for a very long time I would go ahead with cam/head/CAI upgrades this should put you at 480+rwhp. The sacrifice you will make is drivability (don’t let anyone tell you it will not suffer at low speeds) the other issue is should you decide to sell you will not only lose all of your mod money you will likely be worth less than had you kept the car stock. I know folks don’t like to hear this but take a look in the classifieds and you will see for yourself.

If you think you may want to trade up or down in a short time (1-3 years) I would simply supercharge the car with low boost. You will not take the financial hit that you will going the above route.
