    Frequently Asked Questions

    What’s the difference between a twin turbo and a compound setup?

    In diesel performance, “compound” and “twin” are often used interchangeably—two turbos working together to deliver broad, efficient boost across the RPM range.

    Will a Crazy Carl’s kit fit my truck without modification?

    Kits are model/year specific. Always match your engine and year in the product selector or contact CPP Diesel for fitment confirmation.

    Do I need custom tuning with a new turbo system?

    Yes. Major airflow changes should be paired with proper tuning to optimize power, drivability, and safety.

    Are Crazy Carl’s turbo systems good for towing?

    Absolutely. Many packages are optimized for low-RPM torque and cooler EGTs under load—perfect for tow rigs.

    Can I install a kit at home?

    Experienced DIYers can, but professional installation is recommended for best performance, leak prevention, and warranty protection.

    Where are the kits made?

    Crazy Carl’s Turbos are proudly built in the USA using quality materials and proven manufacturing practices.

    Tip: For related upgrades, pair your turbo with proper fueling, intercooling, and head-studs. Need help sizing? Talk to CPP Diesel.
