Modern car computer can precisely adjust the A-F rate of car engine and does not allow making a small change from the external or electronic modification. Basically, once car speeds up in a blink of an eye, car computer is set to increase the gasoline consistency based on the requirement of energy; in fact, this moment is the most gasoline-wasting since the insufficient air can't be completely burned, that is, the increased gasoline waste.

How to make a good use of the wasting gasoline? That's PUGS is coming to being and winning the patent, PUGS completely makes a good use of the intake gasoline while car accelerates or starts by brining appropriate external intake air to enhance the A-F rate and skipping car computer detection. In short, the more air consistency increases, the quicker to reach the A-F rate of ignition, then car computer forces engine to ignite.
