Not Worth The $

With my 30over nozzles and my tune I would drop from 23k to 21k rail pressure so I figured I would give this kit a shot. With my cp3 being low milage I wasn't going to spend the money for a new stroker. Well this kit did not give me any better rail pressure and is a pain to install. I do not recommend
Good up grade hard install

This kit says it is a easy 15-20 min install and you don't even have to take out the CP3 pump. This is true once you take apart the entire top end of the truck. Intake, intake horn, all fuel lines and wiring harness!! Took almost 6-7 hours. Also just a side note if you have a 2001 Duramax like myself you need to know if it is a early model because it has a different size drive shaft and you will have to call Adam at industrial to send you a new one. But other than that it has really woken up my Duramax!! A real good upgrade if you are looking for a good fuel upgrade to run with a programmer, intake, exhaust. Highly recommended just have a shop install it for you.
