I bought this for my 2013 duramax because I did t want the dreaded cp4 blowing up. Item arrived quickly and package awesome. Customer service is the best in the business! I will buy all my truck needs from them again. Cp3 exergy pump was easy to install and runs awesome!

This kit went on fairly easy and after loading my PPEI cp3 tune she fired up and purred like a kitten. It runs a little harder in the mid range and put my nerves to rest knowing that I no longer have a cp4 waiting to grenade. If you don't know what you are doing then let someone who does help you or do it for you.
