Heeello ppl.

Red as you have already figured out is not so good.
Green is Good.
Blue is the Best.

Blue means Turbocharged (as you also have figured out).
What that means (if I remember correctly) is that you are connected to at least a specific number of Ultrapeers (again, 6 if my memory serves me well).

One of the differences between Pro and Basic is that Pro connects to more people. You have thus more chances of getting and maintaining a Turbo-charged connection.
