Actually, don't ECU's have to adjust to change? I know my JB4 didn't feel as fast until the 2nd day. Maybe when you switch to map 0 it's still adjusting and feels faster.

Nope we ran one on the dyno the other day and the change was pretty instant after the 2nd pull it would get another 2-5 hp or so.
