Remote ECU tune · 3.6L Pentastar V6
A custom Stage 1, 2 or 3 calibration for your Dodge Charger / Challenger / 300 3.6 V6, 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 / 300 3.6 V6 makes 292 hp and 260 lb-ft (353 Nm). A Stage 1 tune typically adds 13–20 hp and 15–20 lb-ft, for around 305–312 hp in total. With bolt-ons and a Stage 2 calibration that grows to +20–35 hp, and a Stage 3 build — adding a supercharger or other forced induction, with the fuelling to support it — typically lands at 392–462 hp.

Tuner's notes
Tune-only gains on the Pentastar are small because it is a naturally aspirated V6 with a conservative factory calibration. The bigger improvement is in throttle response and 8-speed shift behaviour. Automatic cars measure about 255 whp stock.
