What to do with afc settings with H/L boost?

[NeXtLeVeL]

Hi i plan on getting a profeb boost controller and Apex safc. And I wanted to run my boost setting low 10-12 and high 18-20 not sure yet. I getting a BigT28 to do those setting and i was wondering. How would I set my afc because if i have it on 10psi for daily driving then switch it for racing to 18 psi or so, wouldnt I be running lean. Or could I set the afc for my high setting then when boost is on low just have it run rich? thanks

One of the bad thing about an AFC is you cannot have multiple settings on the AFC. People usually tune for Hi boost.

I don’t see the appeal of running a low boost level on the street. I would push your car until you can’t go any further on pump gas. Then when you want to hit the track turn up the boost and add c16.
