I'm well aware of how boost creep happens. This is essentially the same thing. Notice when his target boost levels off at the desired level, the actual boost reading continues a couple more PSI higher, I'm assuming this is because the wastegate isn't able to keep up. Terry has mentioned that without the EWG wires the JB4 would have trouble controlling boost levels on map 2, hence my question of if he has the wires. If you'd prefer to call it a boost overshoot or something instead of creep since it's not happening at higher RPM's, thats fine too.
