Your Firebird was designed to handle a lot more power than it put out when it came out of the factory. However, certain compromises between performance and economy have to be struck before a car can be introduced to the market, so your 1999 - 2002 Pontiac Firebird sits with untapped power. Untapped, that is, until now. The Hypertech Firebird Power Programmer was designed to find that power. What’s more, it could not be easier to use. Simply plug the programmer into your car’s diagnostic port and answer the yes and no questions it asks you. After only a few minutes, your car’s electronic control unit will be entirely reprogrammed to make all of your car’s parts work together to crank out more power. Most vehicles sold in America in the last decade, including yours, features a writeable electronic control unit that regulates almost every aspect of your car’s operation. Older models’ computers could not be rewritten, but that changed in the late-90s. The result is tuning made easier than ever. With this Pontiac Hypertech Power Programmer, you can find power and performance in your Firebird that you didn’t know existed, and you will not even have to dig through your toolbox to get the job done.
