I had the opposite with the fury. I couldn't quite spin the 26 fury to 5700 only about 5500. The 26 tempest I can run to 5700. Now with that said I didn't play with the fury much as I liked the way the boat felt better with the tempest.
The fury did hole shot better and was able to run no plugs on my setup. I have to run some reduction plugs on the tempest or it blows out.
