If you think the factory 6.6L Duramax Diesel that comes in 2017-2019 Chevrolet and GMC trucks is a bad ass, you’ll be really be happy once you have one of the new Edge Pulsar + Insight CTS3 kits on yours. This is one part that will not only give you increased power on an already amazing engine, but also allow you to set tunes based on the driving conditions you are in. Want a mileage tune, its there. Want it stock, you got it. Want max torque for towing, you got it. And with the CTS3 you get data monitoring, and safety measures that allow you to run at any performance level while the system monitors for any out of the norm conditions and then takes action to make sure no damage is done to your engine. This is smart stuff that still lets you make real power.
