GMC Sierra Performance Tuners & Programmers

Introduced in 1988, the GMC Sierra appeared as a trim level of the mainstream C/K line. In 1998, the Sierra became a separate model and has been marketed since then along with a Chevrolet twin called the Silverado. Offering more comfort, technology and power compared to its Chevrolet-badged cousin, the Sierra is also more expensive, which is why its sales are 2.5-3 times lower than those of the Silverado. Today, the Sierra/Silverado family has a strong position on the market, having the total annual sales of about 750,000 units on average.
