Why not go for an AUQ you would need the matching ecu as well.
AUM and AUQ are the same bar the ecu. No?
I was told they are different but if not where does the extra 30bhp come from (is it the map ?)
All the power is from just the map, flash a AUM map to the AUQ ecu and engine then you have 150bhp and and flash AUM with AUQ map and 180bhp.
I think the engine codes are related to emission output to keep the EU pen pushers happy.
