Done some research and decided to order a smarty jr tuner for my cummins and noticed good reviews for thoroughbred diesel . They have earned their rep and are great to deal with. Love my new found power and will use them again for the next goodies

Shipping was quick and the packaging was great. Made the turnaround seamless and fast for core return. Injectors are working great and nothing gave me troubles.
