Beg to differ - the stock 3B ECU does have an overboost function. When you hit it, it grounds the fuel pump, causing major engine cutout/surging and you will not get above 1.3 bar until the ignition is cycled, resetting the ECU.

Want to test it? Just take a clamp and clamp off the hose to the wastegate. BTDT.

There is no overboost function in a 3B ECU, you need an AAN, ADU or similar
ECU for that function.
