  • HELLO I AM INTERESTED REPLACING THE CP4 TO A CP3 AFTER SEEING YOUR VIDEO I WILL NOT BE DOING THE WORK MYSLEF IM TO NEW TO THE DIESEL WORLD, WITH THAT SAID WILL YOUR CONVERSION KIT ALSO WORK WITH MY TRUCK WITH EGR AND DPF DELETE ON A H AND S TUNER? Thoroughbred Sku #: IIS436403-CRE PER THE ITEM IT STATES TUNE IS REQUIRED COULD YOU SPECIFY WHAT KIND OF TUNE I WOULD NEED ?

    CHRISTIAN | 4/30/2022

    Yes, https://www.thoroughbreddiesel.com/industrial-cp4-to-cp3-conversion-kit/, your tunes will have to be modified for the CP3. It has an LBZ FCA.

  • Does the kit with the factory fit pump require any tuning after installation or will it work with all factory settings?
