TurboXS Dual Stage Boost Controller Tuning

Can something like the Greddy E-Manage FMU control the needs of a turbo setup with a TurboXS dual stage boost controller? The E-Manage Ultimate has the ability to switch between two different fuel maps... but that's also $400 more.
Has anybody ever used this TurboXS DSBC? And what kind of fuel management did you use? Thanks!
