HEMI & Hellcat Tuning
Custom calibration for 5.7 HEMI, 6.4 Scat Pack / SRT and Hellcat platforms, including bolt-ons, camshafts, boosted combinations, fueling, spark, idle, startup and transmission behavior.

NFG Performance provides custom calibration for Mopar, Nissan and Infiniti platforms — from stock and bolt-on street cars to cammed, boosted and ethanol-fueled builds. Each calibration is developed around the vehicle, its hardware, its fuel and real data from the car.
Performance calibration
Whether the vehicle is tuned locally or remotely, the process starts with the exact modifications, fuel, ECU setup, logs and performance goals.

ECU unlock information →Calibration support for G35, G37, 370Z, Q50 and Q60 platforms with attention to fueling, throttle response, drivability and log-based revisions.
Explore Nissan / Infiniti →How it works
Provide the year, model, engine, fuel, modifications, ECU status, tuning device, current calibration and goals.
NFG reviews the combination and identifies any unlock, sensor, fuel-system, spark-plug or supporting-hardware requirements before calibration begins.
Remote customers submit data logs for revisions. Local customers can complete the same process in person when scheduling allows.
Built for real-world performance
A properly sorted tune should support strong performance while also addressing startup, idle quality, throttle response, fueling, torque behavior and drivability.
Part-throttle behavior, idle control, startup and transitions receive the same attention as wide-open throttle.
Calibration changes are based on vehicle-specific data instead of assumptions from a similar build.
Guidance is available for compatible injectors, fuel systems, sensors, boost changes and supporting hardware before tuning.
