When you would like to add a little bit of muscle to your Cadillac, there are many products available that can help you in your quest, but many are very expensive and require hours of very hard work. That is not so with the Cadillac performance chip. There is no need to put the overalls on for this project, simply locate the engine's computer, and plug the device in to the built-in port. With that simple act, the Cadillac performance chip can add anywhere from 5 to 25 horsepower to the performance of the engine. The device works by getting rid of the old, conservative engine settings, which were designed for everyday driving under the broadest possible range of conditions. The Cadillac performance chip replaces them with settings that can squeeze every bit of performance out of your stock engine. First, it adjusts the air-to-fuel ratio and the spark timings, to ensure that the engine is using the most possible energy from the fuel. Then the Cadillac performance chip removes the top speed limiter, and makes other small adjustments. If your vehicle has an automatic transmission, it adjusts the shift points and shift smoothness, for proper delivery of the new power amounts. Finally, the Cadillac performance chip raises the rev limiter, so that you can use the extra power that is located at the top of the RPM range. To revert you vehicle back to its stock conditions, all you have to do is remove the chip. Our online catalog has the Cadillac performance chip for a great price, from several manufacturers, and it can be ordered online, through our secure site, or by phone, with a toll-free call.
