Customer service at it’s best I had put a post on facebook asking for help for my old 7.3, the owner of the company replied to my comment offering help. He offered advise and walked me through the entire process showing me the parts that would work well at a reasonable price. Just don’t see that type of customer service anymore in todays world. Anyone looking for knowledgeable help with there 7.3 should contact them before buying anywhere else.

Great product Great product. Shipping was a little slow. Said takes 3-5 business days to get. Order it on a Thrusday didn't come until the following Monday. The tracking info was kinda hard to see where the product was and when the updating with the package. Asked all my questions and information that I needed about the product.

Great product Great product. BUT, I wish I knew that the driver side line is not compatiable with aftermarket intake plenums such as RiffRaff. They are too thick and you can not screw the 90* fitting on. I now have an extra line I cannot use and must purchase another passenger side line.

Recieved programs for my Hydra from CNC… I recieved programs for my Hydra from CNC Fab. What a difference it made in power. I tried PHP and Gearhead programs, but CNC had the best seat of the pants power increase of all three companies. The CUMMINS KILLER program is AWSOME!!!
