I've been getting this kind of results for the past few weeks on some mods I have made. I would tell ya'll what the mods were but there is probably no room in the unicorn corral. The lean settings probably won't mean anything to y'all, they are a reference for me. The one I will use is the 3rd one on the list.
The conditions were really windy but I decided to do the tests anyhow. None of the passes were wind aided, the difference from east to west are from elevation changes. The location of tests is in the Texas Hill country. This was just driving, no coasting other than one steep hill that cannot be avoided. I have removed my turbo until I finish my upgrades.
Ignore the 16.65 mile each direction it is 18.65 miles (oldtimers disease)
