you need 32.1 or 32.2 installed first.
... and then they need to go back into your ecu with the same software and give you the OPTIONAL wastegate fix.
if the assh*les at your dealership cannot do this, go to anthother dealer.
under most circumstances (if you complain about lag), dealer should update you for free.
even if you had to pay for the OPTIONAL wastegate retrofit (lagfix), it would be worth it IMHO.
see my bmw SIB bulliten post one up from this.
