I am an electronics expert and computer engineer and the so called chips that they are trying to sell you is only a simple 2 dollar diod with a switch. The diod typically does not do anything to most cars and could cause your car to run improperly over time. I recommend you stay away from chips such as this and stick with jet performance or similar brands. This site is selling a 2 dollar wire for 70 dollars that doesnt even effect most vehicles. Buy a real performance module. You may spend more money but it is very worth it.
