About This Product
2019+ Ram HEMI Performance Tune Files
This is a pre-written performance tune file built for 2019 & newer Ram HEMI trucks running popular camshaft setups including the BTR Truck Norris, Texas Speed Chopacabra, and similar performance HEMI cam profiles.
Designed specifically for the newer DT-platform Ram trucks, this calibration helps correct airflow, fueling, throttle response, transmission behavior, idle quality, and drivability after cam swaps, long tube headers, intake upgrades, and other performance modifications.
This is not a generic upload. Your tune is built around your factory read file, operating system, year, engine, transmission, tire size, gear ratio, and complete modification list.
Built for Modern Cammed Ram HEMI Trucks
The 2019+ Ram HEMI platform responds extremely well to camshaft upgrades, but proper tuning is critical for stable idle, clean drivability, throttle response, transmission operation, and reliable street manners.
