Yes it has changed the sound of dv. It seems like now its relasing quicker. One stronger shorter woosh compared to longer, less sharp whoosh before bypass ;D
 
In those cases you could argue the N249 would be a good thing. BUT, I think removing it does make the piping simpler so will act a fraction quicker...
 
Yeah that is a good thing but sometimes it's judgement seems to be more on the precaitious side when it's not needed.

I have just found something to do over the weekend :), if I don't like it then I'll put it back standard I guess.
