What are the differences between the 2000 and 2005 engine? Another 30 horsepower would be a sizable gain and it obviously doesn't involve forced induction or a larger engine.
Can anyone help?
Thanks!

On top of the better computer software and variocam plus, I think 05+ have better exhaust manifolds with equal length runners. The manifolds on the 986 look like they could be a lot better.
