I haven't got the chance to pull yet with my '17 but compared to my '15 you can defiantly feel the extra power. Just have to see how the consumption is for DEF. On a side note if anyone is looking at new '17s check the paint over carefully. I have a nice run in the paint on the roof next to the middle roof light.
I have the same run in my paint. It's just off center towards the driver's side behind the middle roof light cluster. It almost looks like they painted over a flake of metal or a something.
