These are the best set of power harnesses on the market. This is for an adjustable boost harness and fixed fuel temp harness. The adjustable set up gives you the ability to control fuel rate at your finger tips. They have been built and tested by a CAT master mechanic.
They were developed and tested for two years before being sold to the public. Many have imitated but never duplicated the Diesel Freak brand of caterpillar power harnesses. Dyno results from 10 different trucks show increases in horsepower around 90 hp and torque around 250 ft lbs.
Increases in fuel mileage have been from .5 mpg to as high as 2 mpg depending on application. These harnesses were built to increase fuel mileage and power. They can save you thousands of dollars in fuel costs.
Harnesses are professionally built and tested before shipping. They carry a lifetime warranty and are made in the USA. If for any reason you do not like the results I offer a 100% money back guarantee. Simply return the product within 60 days for a full refund.
These harnesses will NOT work on the C-15 bridge engine serial prefix MBN or the SDP Particulate. They also do NOT work on the C-13 LEE serial or the C-12 MBL
