Simply put, those things are JUNK. I'm sure you will get many opinions from different sources claiming that they boost horsepower, fuel economy, yada yada yada but, I'll tell you honestly that I'm not trying to sell you anything. In fact, I'm trying to keep you from throwing your money away. If these "chips" were anything more than "snake oil", why would they sell for only $69.00 and have an MSRP of $400 ? There are plenty of reputable chips and programmers out there made by Jet, Bully Dog, Super Chips, etc.that ARE $300 - $500 and they sell for that much because they work. The "chips" that you are talking about though show a complicated looking "computer chip" but, when you get it, you will see that it is nothing more than a cheap plastic box with some wires hanging out of it that you are supposed to splice into your IAT ( Idle Air Temperature ) sensor harness and the cheap resistor that is inside the cheap plastic box is meant to fool your engine control module into thinking the air is cooler than it really is ... Cold air is denser than warm air and requires more fuel to maintain the proper air / fuel ratio which SOUNDS like it would equate to more power, right ? Wrong. I have included this link for more detailed information about how your IAT sensor works and the consequences of it being "faulty" -- Faulty because the part is bad or faulty because you have added some worthless "chip" to alter the correct reading is still "faulty". Here is the link: http://www.aa1car.com/library/air_temp_sensors.htm Basically, what it says is "A faulty air temperature sensor that is reading warmer than normal will typically cause in a lean fuel condition. This increases the risk of detonation and lean misfire (which hurts fuel economy and increases emissions). A faulty air temperature sensor that is reading colder than normal will typically cause a rich fuel condition. This wastes fuel and also increases emissions." Neither one of those says anything about more power or increased fuel economy -- In fact, in addition to the REDUCED fuel economy and INCREASED emissions, you also have the detrimental effects of detonation and lean misfire ( burned valves, piston damage, spark plug damage, etc. ) over time with a lean fuel condition or increased emissions that can foul your spark plugs and clog your emission control components with excessive soot caused by the over fueling. The BEST thing you can do is steer clear of anything that claims to "AWESOME" but sell for a fraction of it's MSRP -- If it sounds too good to be true, you can believe that it probably is.
