dont waiste your money on ANY mail order hyperCrap or Jet chip. all they do is add timing and lower fan temps. Not worth 5 bux let alone 250. get a Pro tune. or save up some cash and do a PCM upgrade. i had the stock pcm pro tuned by %*& and it was right on wide open car ran good. i then upgraded to an LS1 pcm gained 15+rwhp(cant really get a fixed gain as i added a 9" at the same time) and the car ran a fukll second quicker in the quarter. NOT saying it was ALL tune or PCM related BUT the drivability that i thought was Great after the original tune. i was blown away by how much better the car runs now. Again save up and do it RIGHT.
