For me (B58 M240i with BMS intake, FF harness, 93 octane, and meth), it has helped correct overboost and create slightly smoother runs. I am sure of it because now I have it disconnected (the wire is faulty) and I am occasionally overboosting, esp with WMI/Map 7. I do currently get serious throttle closures when the car is on Map 7 when I first start driving at WOT, so I don't yet know if EWG control can help with throttle closures, but I am planning to fix the wire and then re-test, as a datapoint. The closures get better as I drive longer. I'll post logs when I get the thing reconnected.
