FROM THE BEGINNING
In the late 1970's and 80's, the Cummins 855 Big Cam was the king of the road when it came to semi-truck diesel engines. It was and still is an engineering masterpiece. At the time of its inception it was not only the most powerful engine available, but the most fuel efficient, the most reliable, and the first engine to meet noise and emissions regulations. We formed a close working relationship with several Cummins engineers and became a trusted Cummins service shop and dealer. Back then we did a lot of experimentation and testing on the Big Cam to figure out how to make more power and eventually developed the first aftermarket twin turbo kit, making over 700 horsepower. With the introduction of the N14 we continued the tradition of performance tuning except this time with computer software in addition to the hardware.
