So...i got the following page/illustration shared with me regarding PSE on the 991 (I was told the source was the 991 technical information manual?), does anyone have access to the equivalent from the 981 technical information manual? I don't BELIEVE that that Cayman and Boxster are different but I KNOW that the PSE is the same for the 2.7 & 3.4. Please let me know, thanks!

Anyone?
