At Andy's Auto Sport, we have a huge variety of GMC Sierra chips to ensure that you have every performance chip option available to you. We go out of our way to carry every major line of GMC Sierra chips, so that whether you are looking for a Jet performance chip or a Hypertech power programmer or a Diablosport chip or anything in between, we've got it for you. Andy's Auto Sport is the ultimate shopping destination for your GMC Sierra performance chip needs!

A new performance chip improves power, torque, and fuel economy by changing your timing, fuel curves, redline, and even shift points where applicable. These improvements can net a substantial increase in performance with minimal effort, as performance chips are among the easiest modifications to install. What's more, a new performance chip can be one of the most cost-effective improvements you can make to your ride, and will complement any other performance mods you might already have.

In the world of modern fuel injection computers are king. But just because you can't tune your fuel injected vehicle with a screw driver doesn't mean that you have to give up on tuning altogether. Aftermarket power programmers allow you to work with your vehicle's ECU to custom tune air/fuel ratios so that you can maximize performance and efficiency. Here at Andy's Auto Sport we have a fantastic selection of power programmers from all of the leading brand names so that you are sure to find the perfect set up to achieve your goals. Whether you want improved mileage, better low down torque or increased top end, power programmers are just what the doctor ordered.
Some performance chips, ECUs, and programmers are so effective at increasing power that it is recommended to also upgrade your valvetrain in order to safely handle your engine's new output, although this change is usually reserved for more aggressive performance chips. In some instances, your factory chip is reprogrammed via a performance programmer/tuner, and can allow for different "stages" of upgraded power characteristics.

Most vehicles come from the factory with fuel mapping that is extremely rich. This is done as a way of idiot proofing cars to keep the motors safe from people who recklessly thrash their rides. However in most cases it is possible to tune the mixture a bit leaner while still maintaining safe parameters. A leaner mixture means increased power and can also improve fuel mileage. The best part is it all happens with a few clicks of a button, and if you want to return your vehicle to stock, these setups are simple to unhook. Step into the world of 21st century tuning with power programmers.
Q: What is a performance chip? Why buy one?
A: Most modern vehicles use computer controlled engine management systems that actively adjust things like ignition timing and fuel delivery to keep your vehicle running efficiently. However many factory systems are tuned conservatively for normal road driving and to keep a high margin of safety for the engine. Performance chips can be added to your vehicle to give a more aggressive state of tune for improved power and performance. With more aggressive ignition advance curves and leaner air/fuel ratios it is possible to see large gains in horse power and torque. The best part is you do not have to make any internal engine modifications to see these gains. Simply add your performance chip and you are ready to go. And if you wish to sell your vehicle you can easily return your vehicle’s ecu to its original programming.

Q: Are power programmers truly "plug-and-play"?
A: Vehicle-specific Power Programmers are truly plug-and-play. Simply attach the programmer to your vehicles ECU or DLC (Data Link Connector). No tools are required, and the programmer will come with instructions. If the programmer is universal, it has to be spliced into your factory ECU.
