This falls under the "engineers vs bean counters" category. But you will see them in race/high performance environments, including Formula 1 & Le Mans.
You can see links to S55 dynos here, as the DME is making incremental gains from each run: https://f80.bimmerpost.com/forums/sh...1#post16507069 |
Thanks for the link Tom. On that F80 post you said

While gains are minimal on a relatively stock engine, these will be prove more beneficial once more performance parts are available, such as tunes and exhaust. A bonus is a mild amount of turbo spool noise during revving.

I read that as "a tuned car will produce more with the reusable BMC filter". But above you mention 10hp. Is that gain expected on a stock G80?
