Remote ECU tune · 5.7 / 6.4 HEMI V8
A custom Stage 1, 2 or 3 calibration for your Dodge Charger / Challenger HEMI, 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 HEMI makes 375 hp and 410 lb-ft (556 Nm). A Stage 1 tune typically adds 15–25 hp and 15–35 lb-ft, for around 390–400 hp in total. With bolt-ons and a Stage 2 calibration that grows to +35–60 hp, and a Stage 3 build — adding a supercharger or other forced induction, with the fuelling to support it — typically lands at 550–625 hp.
