Newer Silverados and rams both have a limiter around 100.
You need to tune both to remove the limiter.
And this is the obd reader I have.

And use this app
“Obd fusion”
But I don’t see how any of those apps would track your etorque fuel savings.
My Subaru has a screen, think we saved .4 gallon over 20k since it’s usually turned off.
We had a loaner Subaru that had 15k on it, and assuming a.s.s was always turned on, it showed it saved 4gal
