Timing Specs for S4
Per the Tech Adenndum that I have...
At idle (675 +/- 25) rpm - timing should be 10
At 3000 rpm - timing should be ~ 34.
There are several items to impact the timing as you may already well know
- knock sensors, Hall Sensor (87 & up), and the Final Stages Output to
just name a few.
I checked my timing with a timing light to see if there was any
shifting/issues - and didn't identify any deviations from the specs
