Remote ECU tune · 6.2L supercharged HEMI V8 (Hellcat)
A custom Stage 1, 2 or 3 calibration for your Jeep Grand Cherokee Trackhawk 6.2 Supercharged, 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 Jeep Grand Cherokee Trackhawk 6.2 Supercharged makes 707 hp and 645 lb-ft (875 Nm). A Stage 1 tune typically adds 40–80 hp and 37–55 lb-ft, for around 747–787 hp in total. With bolt-ons and a Stage 2 calibration that grows to +120–200 hp, and a Stage 3 build — a smaller supercharger pulley, larger injectors and supporting bolt-ons — typically lands at 907–1,007 hp.

Tuner's notes
The AWD system puts down the Hellcat power cleanly, so pulley and tune gains turn into acceleration more directly than on the RWD cars. Stock Trackhawks measure about 560 whp.
