TTS Starter Map Opinions?

[blackdog]

As a base starter map for a 2010 FLHX with A/C, catless head pipe, and Rinehart 4" slip-on which map would be a better choice for VTuning, CTA009 or CTB009.  Aside from the Main Lambda and PE Lambda tables, the cals appear to be the same.  Does anyone know if there are any internal differences to these maps that we cannot see?

Current VTunes were done using CTA009.  Bike runs fine as tuned.  Just trying to determine if there would be any benefit to using the CTB009 map with VE's calibrated using CTA009 base map. Or would this be just a waste of time?
