The Pulsar power module for the 2017-2019 GM L5P Duramax has been a huge hit. For customers looking for performance, unmatched features, throttle adjustments, no traces of a tuner to void a warranty, and ease of installation the Pulsar is the answer. Edge has now improved the Pulsar in Version 2 with new features like Speed Limiter adjustments, improved transmission shifting strategies, manual particulate filter regen, and transmission relearn capability to improve shifting with the added performance. The best part is these new updates are free for current owners and available now by simply updating your Pulsar with the provided update cable or with your Insight CTS2 or Insight CTS3 monitor.
