What kind of fuel economy are users seeing with the trinity on a 2010 chevy duramax?

Our 06 LLY will gain anywhere from 3-5+ MPG on the highway, FWIW.

When I tune my 05 Duramax with the 80HP tune, I gain around 7 to 8 miles better to the gallon. I went from 18mpg to 25mpg and thats driving 70 to 75mph. If I drive at 65mph I have seen as much as 28mpg. I love this tuner

sweet.

I just installed my first predator on my 2007.5 Duramax LTZ and I'm not seeing really any big difference in mileage. The engine does seem to run louder and rougher at times, that almost concerned my. Then I Just took it around the highway a few miles, and reset my MPG average a few times, it looks almost the same as stock tune. 60 or 80hp. Should I try a trinity tuner instead of a predator? What's the trick for 20+ MPG at 75mph?? I was light on the petal...

Also is there anyway to tell if I have the DPF? It's a 2007.5, so I'm not sure if its new enough.

Thanks for any help, I'm excited to see more MPG that is the main reason I bought the predator!
