I have managed to keep the 12v attached for a few months now. In the past I've had to disconnect it about once a week. That and the warm weather seems to be giving me better results than expected without the full kamm and airdam.

About half of this tank I had most of my mods reversed to pass a safety inspection. It felt like I was driving a lead slug. I used to catch a lot of speed on certain inclines on the highway but with the tail, dam, skirts and wheel covers removed I sometimes slowed down coasting those same inclines.
