SCT LLC. specializes in automotive performance and fuel economy solutions for most Ford, General Motors and Dodge / Chrysler gas and diesel cars and trucks. SCT was founded by hard-core auto enthusiasts. SCT employees share a passion for the products they create and the vehicles that utilize them.

SCT's mission is to be the very best at what they do. Customer Support is the reason why we have the largest network of Custom Tuning Dealers in the World. Besides world class customer support, our software/hardware actually does what is advertised. Dealers know that when they have a question, they can get a answer from us. Our expert calibration team leaves no vehicle untuned, and no problem unresolved. SCT dealers and customers have come to trust that what we promote, works. SCT spends considerable time testing every product we sell on both the dyno and on the street. We often turn down opportunities to develop or sell other profitable products because we do not believe in them or because we know from our experience that they will not work as advertised. SCT would rather not sell something to our customers that is a waste of money or has not been proven to be worthwhile.
