Vehicles have evolved from being just a 'tool' for transportation to an advanced and capable machine that can tackle a wide variety of tasks. Jampacked with premium technologies and controlled with the computer, they ensure a superior driving experience. However, most of the factory vehicle computers are calibrated very conservatively and intended to meet the needs of an 'average' driver. For those who insist on the latest trends in technology with every passing season and want to get the most out of their vehicle, manufacturers offer more and more sophisticated performance chips and programmers that will turn any daily driver into a performance beast.
We gathered an exhaustive selection of the finest performance chips and programmers to help you unleash the true potential of your GMC Sierra. Get these top-notch products to fine tune your engine for a huge jump in horsepower and torque. GMC Sierra performance chips and programmers contain performance 'tunes' developed and thoroughly tested with the dynamometer to provide you with exceptional function and quality you deserve. You can not only boost your engine's efficiency using performance chips and programmers, but also monitor coolant temperature, exhaust gas temperature, intake air temperature, turbo boost, etc.

- Performance ChipsSpeedo Calibrators and Tranny Controllers Let You Re-Engineer Your RideMany auto enthusiasts are driving around with speedometers registering too low a speed because they've mounted bigger tires on their vehicle. This effect occurs because larger tires have a greater overall circumference (distance around the outer edge) than smaller ones do. A tire with a larger circumference will cover more ground per revolution, and it will also make fewer revolutions in a mile than a tire of smaller diameter.
- Performance ChipsData Monitors and Loggers Provide Access to Important Drivetrain InfoIf you're tuning a modern engine, there's a lot of information you'll need to know in order to make educated adjustments and avoid trial-and-error guesses. Keeping track of air/fuel ratios, fuel pressures, boost pressures, and rpms is difficult at speed, and trying to commit them all to memory is almost impossible - assuming you even have readouts for these items. Maybe all you need to do is closely watch how temperatures and other things are affected by stop-and-go traffic. Or maybe you take your vehicle on track runs. If so, you already know splitting your attention between gauges and driving just causes you to lose focus on both. Because you can't take notes while driving, we offer a practical and effective solution for the tracking of engine data - recording it electronically for later playback.
- Performance ChipsWhy Should I Add a Throttle Controller?Modern cars and trucks are constantly evolving, mostly due to advancements in electronics. This allows vehicle systems previously controlled by mechanical hardware to be run by computers that have processing power undreamt of several short decades ago. When applied properly, this processing power can wring out higher levels of a vehicle's built-in power and responsiveness, without physically making any engine upgrades. One such system found on today's fuel-injected vehicles is electronic throttle control, commonly known as drive-by-wire.
- Performance ChipsAre Superchips Really Super?In today's ultra-competitive automotive world where fuel consumption, horsepower, and emissions are paramount, modern vehicles are controlled by computers in order to meet these opposite and conflicting demands. And presiding over the multitude of separate computers on any vehicle is the ECU (Engine Control Unit) - sometimes called the ECM (Engine Control Module).
