Full load. You want to see 25+ at WOT from 5000 rpm and up. What that corresponds to at idle is difficult to say.

oh ok i thought so but wasnt sure so pretty much i would have to do this while on a dyno

[C. Ludwig]

I'm going to say don't do this because it's dangerous working around a car strapped on a dyno when it's at full load, but I'll actually shoot the timing while the car is loaded on the dyno. This way you know for sure what you're getting. Anything else is just guessing. Manipulate the CAS until you get what makes best power and lock it down.

where should i set the timing at to start since its not under a load?

Factory is a good place to start. The S5 factory timing is fairly close to optimal.
