Add another data point for my car. Thank you for creating this thread! I really hope my engine is okay. 5 out of my 8 exhaust valves were tighter than spec, with 4 being way tighter than spec. All the intakes were okay.
My engine runs a lot smoother after the valve adjustment. The low rpm hesitation that is commonly associated w/ the DBW cars has been reduced significantly.

awesome printout. Who did the valve adjustment? Did they print that out for you?

Have recently done a few 06+ cars. Both had a few intake and exhaust valves that were slightly tight, nothing grossly out of spec (below 0.008). Both had 60k miles+.
The worst valve was a thou or two tight on the exhaust side, and a few were a thou or two loose, mostly intake side. Adjusted all valves to the upper range and cars ran great.
