I have simply not had the opportunity test the car yet, been to busy worrying about and "fighting" the vacuum leak. And I am taking it a little easy as I am still running it in. But I am sure I will get the opportunity sooner than later.
Jaykay, regarding the 997 intake manifold (plenums?), I read somewhere of a guy using it on an 986S engine with the help of an adapter plate. It has some of the bolt holes in the wrong place as the 997 heads are different from the 986S/996 heads as I assume you know. But the intake ports are in exactly the right place. Out of the six bolt holes on each side, two did fit perfectly, I drilled the manifold for two, and made an adapter plate fastened to the top of the manifold to take the remaining two. And I guess I went for it as it is geared to the bigger engines and also, not that it is a big issue, it looks dam good under the clear engine cower, in my opinion.
I now have "problems" with the blue air intake boot at the throttle body that contrasts the red PORSCHE letters on the manifold. As the boot was real hard to find, I should maybe change the letters to blue for better "harmony"??....... so many details to worry about......
but in the meantime I continue to ride with a big smile at every opportunity.
