I don't think the average person understands what cam deviation values (as it apply to the Porsche Vario Cam system) represents.
What does the Camshaft Deviation value really represent???
Deviation of cams from factory set point in degrees of timing in relation to crankshaft position???
Deviation from factory set point in degrees of timing in the relationship of Exhaust cam timing to Intake cam timing??

OR????????

Secondly I don't think the Cam deviation values change with RPM unless there is an issue with the mechanic's.
The important thing is to have the engine fully warmed up when taking readings.
