I agree with the Greddy kit or Revhard. Dont get sucked into that you ahve to run a standalone yet. if you run teh stock set boost of a greddy or other named brand kit, then you will be fine. they send everything needed for your car to operate correctly. When you finally want more, then you can persu the avenue of standalones or piggy backs. but till then, just use the stock kit. You'll be fine and your car will not have an issue at all. Just rememebr do NOT turn the boost up at all. leave it set to what they set it to.....
Good luck.
