About This Product
Ram HEMI Performance Tune Files
This is a pre-written performance tune file built for 2013–2018 Ram HEMI trucks running popular camshaft setups including the BTR Truck Norris, Texas Speed Chopacabra, and similar performance HEMI cam profiles.
Designed for real street-driven Ram HEMI builds, this calibration helps correct idle control, airflow, fueling, throttle response, transmission behavior, and drivability after a cam swap, long tube headers, intake upgrades, exhaust changes, and other common bolt-ons.
This is not a generic upload. Your tune is built around your factory read file, operating system, year, engine, transmission, cam setup, tire size, gear ratio, and full modification list.
Built for Cammed Ram HEMI Street Trucks
Cammed HEMI trucks need more than a basic bolt-on tune. After a cam swap, the factory calibration can struggle with idle quality, airflow control, fueling, throttle response, torque management, and low-speed drivability.
- Built specifically for 2013–2018 Ram HEMI platforms
- Supports BTR Truck Norris, Texas Speed Chopacabra, and similar HEMI camshaft setups
- Corrects idle airflow, spark, fueling, throttle response, and drivability
- Designed for real street performance, clean starts, and better manners
- Built from your actual factory read file — not a one-size-fits-all upload
- HP Tuners required for reading and flashing your vehicle

Important PCM / HP Tuners Notice
2013–2018 Ram HEMI vehicles require HP Tuners for this tune file. EFI Live is not supported for this HEMI product.
Some Dodge/Ram applications may require an unlocked PCM or additional HP Tuners licensing before flashing. Please verify your setup before ordering.
Performance & Build Responsibility Notice
This is a performance calibration for cammed Ram HEMI vehicles. All supporting components must be properly installed and in good working condition before flashing.
Poor installation, weak fuel systems, vacuum leaks, exhaust leaks, incorrect cam install, or mechanical issues can cause problems no tune file can fully correct.
Secure Flashing Reminder
Always flash with a stable power source and wired connection. Do not interrupt the flash process once started.
