I think, and don't hold me to it, it should go something like this:

5.5L V12TT: 12psi
6.0L V12TT: 22psi

After my tune I was pushing 14~16psi

Dayyyum. That's some pretty stout numbers on the 6.0 liter. Thanks for the feedback.

I will get you solid numbers if I can find them on some spec sheets. The above numbers are from what I remember reading.

Wow...makes me think I should have spent the extra 30k for one of those CPO '06 S65's I have seen for 70k.

I have seen them for much le$$, but I could not own one whithout warranty.
