Does your car have a "manual" shift mode?
I've often found that you can get an automatic to upshift SOONER using manual mode than the default automatic programming permits. That will help as well.

Thanks Metro for the response. I actually mocked up a grill block with cardboard and I am not sure if it is making a huge difference or not. I do have a bluetooth OBD2 connector + Android app to monitor temps.
Yes my car has the manual shift mode and I have been using the exclusively. I actually achieved 41.7MPG on this past tank, my record is 41.9
Something I need to test out after this tank is if it is better to neutral coast or DFCO coast. I will test it out on a full tank. I still need to research on here which is better as someone on the Veloster forum stated the instant MPGs I see when neutral coasting are inflated because it is idling.
