I've thought about that. I have the bottom portion of both triangle grills opened up as well. But, I did pull a hand calculated 38mpg tank last month while on a road trip. My Fuelly still has me above 32mpg for 13K+ miles, so it's still the best mpg vehicle I've ever owned.

I might close off the triangles again. The newmission tube will still have access to non-engine compartment air, it just won't be impact air. I'll run a test like that over the winter, but winter gas might skew my results.
