Squeeze out additional performance from your pickup truck using our Sierra tuners. Trucks and other modern vehicles like your Sierra use computers to control the fuel injection sequence and to determine how much performance and power you get out of your pickup. It's possible to change up the way your truck handles by adjusting the settings on that computer. You can do that with truck tuners. These specialized devices work with your computer to control how your vehicle handles. You attach them to your pickup and they will change around settings to do things like make your truck faster, make it more powerful, help it be more compatible with new engine parts or to be more efficient as you drive around. We offer many different tuners at American Trucks, and some are simple to use while others are more advanced. Each option for your truck will be compatible and will work for you, but some will work better than others depending on what you want to accomplish. Add one of our tuners and work with professionals to help you get the best performance increase from your investment, or select a simple tuner that changes performance settings all on its own. We also offer performance-enhancing parts like exhaust kit upgrades, cold air intakes, and Sierra throttle enhancement kits like a throttle body. With some of our upgrades you can make your truck faster and more exciting to drive around and they're absolutely worth the investment. We even have modification kits that can dramatically improve performance figures. Select one of our supercharger kits or turbochargers and get as much power out of your truck's stock engine that you can for maximum performance.
