how much boost with stock s4 ecu (+SAFC and 720 secondarys + walbro pump)

hi guys...

how much boost can i run with the stock s4 ecu before i'm running onto the lean side?

how much boost can i run with the stock s4 ecu + SAFC + 720 secondarys + walbro pump before i'm running onto the lean side/getting onto the knocking-side because of the no time-retarding?
