Thanks for sharing.
I remember the other thread that linked to an Indy Red M5 with the Eisenmann's. It was also loud on the dyno.
Edited to add:
Ooops, nevermind. It was actually a Supersprint exhaust. M5 Supersprint Exhaust

assuming a standard 15% loss at the flywheel they should be getting in excess of 440bhp ?
If so, these cars are dynoing (is that a word ) just slightly less than where they're suppose to.

DMS was there also for research purposes studying the US ECU program for future upgrades. DMS sent a representative from the UK just for that weekend. He pulled out the ECU on one of the cars and mounted the thing on some futuristic holder and downloaded all the software then sent it to the UK to be analyzed. DMS guy named Darin was pretty cool and very knowledgeable, he said they have several in Europe running 545+ with their remap. Darin did not remap any cars on this visit because they want to study the US version of the ECU which he said is severely crippled and detuned compared to the rest of the world.
I hope they can 'unleash' the US M5 motor and get similar results with the remap.

Is 15% a sort of rule-of-thumb?

Well I was really surprised with the Eisenmann result. They claim + 8 bhp.
I was ordering one but now with this result I need to think again about it ...

Also its interesting that charcoal filter removal did not do anything for the car in P400 mode but in P500 mode it got 10HP extra. This leads me to believe that the 550 would not really benefit from the charcoal filter removal.

question: i'm not overly familiar with dyno testing, but these figures seem low no?
On the issue of charcoal filter removal, these tests imply unreasonably that the filter removal may help, may not help, or may hurt. At the extreme, one might conclude that the filter removal added about 16 RWHP--which would mean about 19 crank HP. I'm not yet ready to attribute any increase in HP to the filter removal. I'm keeping mine until I see much better evidence. The dyno tests reveal some of the follies of trying to draw conclusions from one-time dyno testing in particular.
