I must say, when I bought the fury I was a tad disappointed with the overall performance. Not as bad as I was disappointed with the performance of my twenty thousand dollar softail when I first bought it, but still disappointed nevertheless.
It already had the cobra sweepers, but with the stock cobra baffles in them and stock air filter and no fuel management you can imagine that there wasn't much in the line of get up and go.
After this mornings ride, that problem no longer exist for me.
My recipe is: swapping the stock baffles for thinder monsters, cobra powerflo and cobra Fi2000r @1.2.2.
This thing shags pretty well indeed, now.
Thanks for all the information on this forum, as thats what it took to make me hip!
