Nope, just one map.
If you're running 25#w/c16 at the strip, you wont be at 6# long enough for the "6# street tune to pump gas" to make a difference.
And vica-versa for the street. Tune 93 at 6# and you're good, you'll just be confined to 6#'s on the street, if you're cool with that.
This is just what I would do on my bike. And I log and double check my tunes ALL the time. If you or whom ever tunes your bike feels comfortable with 2 different maps, go for it.
