    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 Buick Rainier. Get these top-notch products to fine tune your engine for a huge jump in horsepower and torque. Buick Rainier 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.
