The Pulsar for 2015-2018 JK Wrangler vehicles is an extremely innovative product that not only delivers power and features but also addresses a key barrier for numerous JK Wrangler owners; the PCM swap process. Pulsar requires no PCM swap and delivers instant power, controlled on the fly using your cruise control buttons. Prior to Pulsar, consumers needed to mail in their PCM to swap with an unlocked unit to flash tune their Jeep. While Superchips process for PCM unlocks is the most seamless on the market today, we've listened to our consumers and understand that not everyone is willing to mail in their vehicle's computer. Enter Pulsar for the 2015-2018 JK Wrangler (along with 20 extra HP that we feel like a boatload more as you drive!) For even more features for your 2015-2018 model, checkout the Pulsar+Flashcal kit (pn# 42450-FC)
