Pulsar XT is an all-new take on drivability and calibration for your 3.6L and 5.7L Ram 1500. Unlike any other device on the market, Pulsar XT is an innovative inline module engineered to keep your factory PCM untouched, with no PCM swap or unlock required. This is the most advanced and easiest way to disable your V8's MDS system to eliminate 4-cylinder mode and keep that Hemi running on all 8, all the time. The built in throttle pedal sensitivity control also helps you fine tune your pedal feel to eliminate throttle lag and make your Hemi drive like you want it too. Enjoy Pulsar XT's shift-on-the-fly pedal programming, with 7 levels changeable through your factory steering wheel controls. The smartphone app allows you to adjust your speedometer for larger tires, transfer case ratio changes and gear ratio changes. Along with adjusting TPMS settings, disabling your Auto Start/Stop, and checking and clearing DTC's. You'll love the way your Ram Hemi reacts with Pulsar XT, with improved throttle response, tire size calibration, and improved drivability running in V8 all the time. You'll wish you would've installed Pulsar XT sooner! *Fits new body style E-Trq and Non E-Trq models **Trucks/Trim Levels equipped with paddle shift not currently supported
