  • Description

Tune Your L5P 6.6 Duramax In Minutes with No PCM Swap!

The V3 Pulsar builds on the already impressive potential of the original Pulsar for L5P and features an entirely redesigned performance strategy. Pulsar V3 now adjusts 4 major components to build power safely: injection pulse width, injection timing, fuel rail pressure, and airflow. We've also revamped our shift strategy for improved shifting across the board. The new V3 performance strategy adds 50% more power as compared to the original. The V3 Pulsar: The Best Just Got Better!

The V3 Pulsar is all about bringing together powerful tuning, safety features, ease of installation, and direct control over your driving experience. The V3 Pulsar, completely changes the driving experience to optimize performance and drivability in every setting. Whether you're towing or daily driving, the Pulsar provides an instant improvement in performance, and throttle response. The Pulsar also includes adjustment features that allow you to account for any changes you've made to your truck. Calibrate your speedometer for tire and gear changes, read and clear diagnostic trouble codes, adjust your TPMS settings on your new wheel/tire setup, or even adjust your speed limiter. After installing the Pulsar, the only thing you'll wonder is why you didn't equip your L5P with the Pulsar sooner.

We took the Pulsar to the track to showcase the gains that you can get in a pure performance setting. We tested multiple runs both stock and on level 5 of the Pulsar. The gains were extremely impressive! We saw an average gain of nearly 3/4 of a second in the 1/4 mile with no changes outside of the Pulsar tune. Stock: 14.93 @ 92.32 Pulsar L5: 14.17 @ 98.44
