[scifi]

I recently put on delta wing vortex generators on a 2005 scion xb with good results so far of course it is very square and flat sided. Ive been using a kiwi scanner to keep track my latest run is up from 29.3 mpg to 35.2 mpg even stopped by two places on the way home I always reset the kiwi and drive the same speed 60 miles per hour, 30 miles each way.
