Sorry for the super late reply. Just found my notification
I don't have any in stock but you can send your for servicing.
Now speaking of pounds ... that's too complicated.
I assume it's 220cc/min and you want to upgrade to 250cc/min
Don't have any in stock either.
I know the m5 uses the 260cc/min and that would work for your application if you intend to boost the engine.
At least I can confirm that the upgrade does make sense for you application and is in fact recommended.
If you decide to upgrade, just check a big supplier, they normally have the tables with flowrates and you can pick up the part number for your use. Stay with the same manufacturer and you'll be good
