Your data so far shows considerable variation tank to tank. Still, the response to mods seems clearly positive. :thumb

KB,
I really don't understand the differences from tank to tank either. I know I am not on a oval track, so it must be wind, hills, construction, etc. I am only stopping for fuel and excercising at the rest stops. No stop and go traffic, just set the cruise and go. Roads are clear and haven't had any traffic to speak of.
Taking the square opening off didn't seem to make any difference on the next two tanks, although I seem to get more lookie looos with it off.
