more dyno stuff.... 

Had to finish the tune after swapping to the small headers.   Tried a few things while it was on there.

First up; some time ago read something on the internet, that throttles may flow better/make more power just under 100% open rather than 100% open. 

Yeh nar; blue: 96% open,  tried 98%  as well same deal just a bit closer to red (100%) line.    Maybe it needs even bigger throttles? they are 47mm




Next is  with the trumpets removed.  the below removed all together


was expecting some big losses,  but not quite like this!   over 10kw through the whole powerband.
