Remote ECU tune · 3.6L Pentastar V6
A custom Stage 1, 2 or 3 calibration for your Jeep Wrangler JL 3.6 Pentastar, 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 Wrangler JL 3.6 Pentastar makes 285 hp and 260 lb-ft (353 Nm). A Stage 1 tune typically adds 15–30 hp and 15–30 lb-ft, for around 300–315 hp in total. With bolt-ons and a Stage 2 calibration that grows to +25–45 hp, and a Stage 3 build — adding a supercharger or other forced induction, with the fuelling to support it — typically lands at 405–445 hp.

Tuner's notes
Most of the tune gain is in throttle response and torque below 3,500 rpm, which suits oversized tyres. eTorque-equipped JLs aren't compatible with some supercharger kits.
