Finally, another option for tuning your L5P Duramax. The Edge Pulsar 22603-3 is an incredibly innovative in-line tuner and the latest option for tuning the L5P Duramax to hit the market while integrating the crisp CTS-3. It produces up to 90HP & 156 ft-lb with Shift on The Fly tuning that is controlled from the CTS-3 and has a built-in throttle booster for increased throttle response and power. 

It's not only power you'll receive with this unit, but you'll also unlock the ability to change your tire size between 29"-50", High-Idle between 700 - 1100RPM, and switch between tuning on the fly.

Safety is always a priority, especially when you're dealing with a brand new L5P. The built-in EGT Backdown features will decrease power if the EGT's start climbing higher than optimal levels, set at 1500°F. Not only that but if the Pulsar module ever senses a slip in your transmission, it will decrease power to ensure the safety and longevity of your truck.
