So many people need to learn this. Do it right the first time. If the place can't get the product you want, don't settle on something else (which I learned the hard way). Or if you can't afford it then wait. You get what you pay for. Eric at IPS has done a good job tuning my car so far. After talking to Brian lately for just a bolt on car IPS does seem to cheaper but when you get up to a heads cam car the price is about even from what I have seen and been quoted. Again, it's not all about price.
