You ABSOLUTELY need to compare mileage on the same route in the same direction. You would not believe the difference in economy when travelling in the opposite direction when taking a trip. The amount of average elevation change would startle you.
I used to make the same 250 mile trip just about every weekend. The trip to Billings would get me about 19.5-20 MPG. Going back to Jefferson City (just south of Helena) I was only able to get 17.5-18. The results were repeated dozens of times. After some research, I see that the elevation of both cities differs by about 2 feet. Wow. Head wind maybe? Lots of things to consider here. I see also that you thought your RPM was higher while using the Gryphon programming. The only three ways that the programming is going to affect are that either the gear ratio value in the Gryphon is incorrect giving your speedometer an accuracy problem and you were actually going faster than actual.... OR The tire size selection is wrong causing the same issue...... OR The torque converter clutch isn't applying.....
