DODGE DURANGO SRT HELLCAT 6.2L SUPERCHARGED HEMI V8 (2021 and 2023) - STAGE 1 PERFORMANCE SOFTWARE TUNE

OVERVIEW

The Dodge Durango SRT Hellcat is one of the highest performance SUV platforms in the Dodge lineup and responds very well to proper ECU calibration. AMT performance tuning improves throttle response, drivability, and optimized torque delivery while maintaining smooth operation.

Our Stage 1 calibration is designed for stock or lightly modified vehicles and improves the overall feel of the vehicle without compromising reliability. Stage 2 is intended for vehicles equipped with supporting intake and exhaust modifications to take advantage of the improved airflow and deliver stronger overall performance.

STAGE 1 CALIBRATION

Stage 1 consists of an individual recalibration of the engine management system, including optimization of key parameters such as ignition, injection, throttle response, torque limiters, and related ECU strategies.

All engine parameter values at this stage remain within sensible operating limits for the platform. Stage 1 is designed to improve performance, drivability, and responsiveness while maintaining reliability.

STAGE 2 CALIBRATION

Stage 2 is intended for vehicles equipped with supporting intake and exhaust modifications that improve airflow. The calibration is adjusted accordingly to take advantage of the hardware changes and deliver stronger overall performance.

Required supporting hardware for Stage 2 includes intake and exhaust upgrades. Headers are also recommended for best results. Rear O2 delete for decat applications is included in Stage 2.
