Factory tq on my 16’ is 800..... I would hope any tune would be more.My truck stock scaled out at 7,500lbs, don't know what the parts that fell off, and no def, made it change to.
Im not saying I get great mpg's all the time. Just around northern MN where I am for the summer. And when driving very nice not in a hurry.
The staties hear drive low maroon cars with a white hood, with headlights off, by the time ya see them its to late. So its best to go at max 2 or 3 over the limit. BUT, still have less traveled paved roads to kick it in the pants if having the need.
Driving all day on the interstate at 65-80 it changes things.
No matter what, its still a lot better than my brothers ford ecoboost for a heavy brick. And that's strange.
Setting 3 I run on, is more than 800 tq.
