After a tire upgrade or re-gear, your Jeep's speedometer and shift points can be off. Wrangler JL, JK and TJ and Gladiator JT owners use programmers and tuners to recalibrate for tire size and gearing, adjust vehicle settings and, with some tools, change engine tuning.
This category includes Z Automotive Tazer, Tazer Mini and JK Blaster programmers, aFe SCORCHER GT and GT PLUS power modules, handheld tuners from Diablo Sports and Superchips, and HP Tuners tuning tools. Features vary widely, from simple tire size correction to full engine tuning, so compare each product's capabilities. Tuners are specific to model and year, and some engine tunes may affect emissions compliance or warranty coverage.
Shop programmers from Diablo Sports, Superchips, AFE Power, HP Tuners and Z Automotive. Also see throttle control and ring and pinion gears. Enter your Jeep in the vehicle selector to narrow the results to parts that fit your model and year.
