Well, in the spirit of being thorough, i recently ran my tank dry and filled up with 93 octane. I uploaded the new custom 93 tune, and the shifting situation i had with the 87 octane has vanished..plus the 93 octane is even more fun to drive (which i didn't think was possible) than the 87 octane...
love these new tunes!! Bill rocks!
