We'd expect to see the same from this platform (S58). We've got a shipment coming in early next week, if someone local wants to purchase and dyno - we'd be happy to share results.

IMHO - wait until after 1200 miles, then install since dealers will replace the filters under the service. You won't want them tossing your brand new BMCs.
I’d love to see dynos that support that. I’ll buy two today if that’s the case.
