Well, been driving most of the night LOL. Here it goes
All interstate driving at 65 MPH with the cruise set, went 50 miles, turned around and drove 50 miles back. I reset the MPG as soon as I engaged the cruise which was at the same point each time I started. MDS is ON.. I know it's the computer's MPG but here it goes.
Stock tune that came on the truck 20.2 MPG
Perf 87 Tune running 89 gas 21.8 MPG
MPG Boost 21.8 MPG
I find it weird that the Perf 87 and the MPG Boost got the same MPG
So there you go, as soon as I dump the 89 gas I have, I'll fill up with 92 and test that tune.
