Remote ECU tune · 3.6L Pentastar V6
A custom Stage 1, 2 or 3 calibration for your Jeep Wrangler JK 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 JK 3.6 Pentastar makes 285 hp and 260 lb-ft (353 Nm). A Stage 1 tune typically adds 15–20 hp and 15–25 lb-ft, for around 300–305 hp in total. With bolt-ons and a Stage 2 calibration that grows to +25–40 hp, and a Stage 3 build — adding a supercharger or other forced induction, with the fuelling to support it — typically lands at 395–435 hp.

Tuner's notes
Covers the 3.6 Pentastar JK (2012-2018); 2007-2011 JKs used the 202 hp 3.8 V6 and gain less. With 35-37 inch tyres, re-gearing does more for acceleration than any tune.
