Edge Diesel Evolution CTS2 Performance Tuner Power Increase for 2005 GMC Sierra Duramax


Can you tell me the performance gains HP and torque that a Edge Diesel Evolution CTS2 Performance Tuner EP85400 would have on a 2005 GMC SIERRA 6.6l diesel. I use the truck for towing a 31foot Fifth wheel and is not a daily driver. The truck has only 58000 miles on it. Can you tell me is there any adverse affects that by using these tuners can have on the truck over time. Hope you can help. Thank You in advance

For your 2005 GMC Sierra with a Duramax diesel engine the Edge Evolution CTS2 programmer part # EP85401 will give you up to an additional 100 horsepower and 210 ft lbs of torque.

That's a lot of power to give a vehicle, but since your mileage is so low you should be fine. The transmissions in your trucks don't really like any more power than stock so long term you will wear that out quicker if you beat on the truck a lot.
