Overview:

The Diablo Sport Pulsar XT is a cutting-edge inline tuning module designed specifically for 2019 to 2024 Ram 1500 trucks equipped with either the 5.7L Hemi V8 or the 3.6L V6 engine. Unlike traditional tuners that require swapping or unlocking the factory Powertrain Control Module (PCM), the Pulsar XT seamlessly integrates without altering your factory PCM. This innovative device is ideal for Ram owners who want to enhance drivability, eliminate the Multi-Displacement System (MDS) on V8 models, and gain precise control over throttle response and vehicle calibration—all through an intuitive smartphone app.

Whether you’re looking to maintain your Hemi’s full V8 power at all times or fine-tune your pedal sensitivity for a more responsive driving experience, the Pulsar XT offers a comprehensive solution with minimal installation effort. It’s the perfect upgrade for enthusiasts seeking improved throttle feel, accurate speedometer calibration for larger tires, and convenient access to vehicle diagnostics and settings.
