The A map was a conservative tune and the B map was a more aggressive tune.

I have emailed Jack at Unichip and they will be coming out with a PnP tuner for the new 5.7L Tundra but won't be for another year. If I remember right it took like 3 or 4 years for them to come out with the first gen tuner, but it was very user friendly and really provided performance gains.
