Remote ECU tune · 6.2 Supercharged HEMI
A custom Stage 1, 2 or 3 calibration for your Dodge Charger / Challenger Hellcat, built by hand by a real tuner from your own stock file and datalog, and back with you within three hours of the file arriving. We tune these cars remotely, worldwide: you read and flash with your own HP Tuners interface, and you pay only once the tune is delivered.
Stock vs tuned
From the factory the Dodge Charger / Challenger Hellcat makes 707 hp and 650 lb-ft (881 Nm). A Stage 1 tune typically adds 20–70 hp and 18–65 lb-ft, for around 727–777 hp in total. With bolt-ons and a Stage 2 calibration that grows to +45–100 hp, and a Stage 3 build — a smaller supercharger pulley, larger injectors and supporting bolt-ons — typically lands at 807–977 hp.
