Remote ECU tune · 6.2L supercharged HEMI V8 (Hellcat)
A custom Stage 1, 2 or 3 calibration for your RAM 1500 TRX 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 RAM 1500 TRX 6.2 Supercharged makes 702 hp and 650 lb-ft (881 Nm). A Stage 1 tune typically adds 25–45 hp and 22–41 lb-ft, for around 727–747 hp in total. With bolt-ons and a Stage 2 calibration that grows to +80–100 hp, and a Stage 3 build — a smaller supercharger pulley, larger injectors and supporting bolt-ons — typically lands at 852–952 hp.

Tuner's notes
Stage 2 on the TRX means a smaller supercharger pulley calibrated together with the tune. Above a 2.85-inch upper pulley, the 700cc factory injectors become the limit, so larger injectors are needed.
