Default B-Spec Tune

Does anyone know anything about the reliability of the B-Spec tune by build journal? I'm about to have my car flashed with the software in the next coming days but I want to make sure its a trusted first.

I purchased the tune from them about a month ago. No issues so far.

Do you offer custom tuning as well? How long/what is your background in tuning? This is the first time I heard of this option for the E46 M3.

Sounds like the stage 3 B-spec is the move
