Features:
The L5P Duramax Pulsar V3 is the most advanced L5P performance product on the market. The addition of the industry-leader in digital gauges provides the potent power and visibility combo that has no competition. The Insight CTS3 is a category killer in the digital gauge segment with it's high-resolution, 5" color touch screen with full swipe capability and edge to edge graphics. When the Pulsar V3 and the CTS3 Insight are paired, you get more than just impressive gauges. You gain full control over the Pulsar including power level adjustment, transmission slip protection on/off, EGT backdown adjustment, high idle adjustment, throttle sensitivity adjustment, and more.
Note: This product cannot be shipped to or used in California.

Hey Jim, thanks for the review, and sorry to hear this is happening. Since the truck runs and communicates normally as soon as the Pulsar is removed, I’d definitely be looking at the Pulsar or its connection to the ECM rather than digging any deeper into the truck’s factory communication system. You’ve already done a ton of troubleshooting, so at this point I’d get Edge involved and have them test or warranty the Pulsar module before digging any deeper into the factory CAN network.
