Lambda Target

hey, forgive me if this is a stupid question or if I've completely missed this in the tutorial videos

when setting up a lambda target table for a turbo'd car how do you pick what targets to use?

when we are mapping the main fuel table we are aiming to match the lambda targets we set, I'm worried about setting targets too rich/lean

again I apologise if this is a stupid question

Here's a couple webinars coverting AFR's on Boosted applications:

And naturally aspirated:

So basically the targets that we choose are (understood)and general targets ?I will be watching the video shortly .

@Joseph - Yes, you will start with safe known AFR starting points for your particular engine/application and then you will want to test and find how your engine responds to richer and leaner AFR.
