Modern diesels have boatloads of power and torque and tend to yield very decent fuel economy even while towing or hauling the heaviest of cargos. One thing’s for certain though, you can never have too much power when towing heavy loads up steep grades.
And that’s the thought that crossed our minds when we took a ride in our buddy’s tow/chase crew cab Chevy Duramax diesel truck. Not only that, but we also noticed the lack of pertinent powertain information on the dash. We would like to know more than what the stock gauge cluster tells us.
Both of those issues were resolved when we made a call to Edge Products and ordered up one of Edge’s new Evolution CTS programmers to see just how much power it could unleash from our Duramax. Installation was a breeze since the Evolution Programmer plugs right into the OBD II diagnostic port. The hardest part was mounting the Evolution CTS digital gauge display (snapping the unit into the mounting bracket that mounts to the windshield using a suction cup). From there all we had to do was follow a few simple steps through the menu of the programmer and in no time at all we had ourselves a lot more power than what we’d previously enjoyed.
We took the truck out for a test drive and felt a lot more torque which instantly put a huge smile on our faces, and as soon as we laid into the throttle we realized just how much power we had unlocked. We set our truck to the “Towing” setting and were very happy with our newfound powerband. The Edge Evolution CTS programmer made our truck pull like an aggressive freight train—even with a huge welder and lots of scrap metal strapped down in the truck bed! Needless to say, we’re very impressed with the results of the Evolution CTS programmer. But one of the coolest things about it is all the gauges we can now monitor from its screen—ones that the factory instrument cluster did not include. Not only that, but we now had an onboard diagnostic trouble-code reader, as well as a display monitor for a optional back-up camera that can be introduced into the Edge CTS system.
