I don't use superchargers often, in fact I've used the DE supercharger for two trips so far and that's it. I had no problems on either trip, and I don't remember a difference between them. One trip was back in September, but my 2nd trip was recent. I think I charged in the first and third spaces, and in fact I got ~97 kW / 330 mph on Monday 1/20. Maybe they fixed whatever the problem was just before MLK weekend.
