Leaning actually made the turbo spool better = boost earlier = better VE from 2.5Krpm till 5Krpm resulting in a better accelaration. Also oil/fuel contamination was reduced and econmy was increased.... so why not?

Insanely enough I tried 15-16AFR at low boost (1-6psi) but failed as the engine was actually loosing power then.

After 6Krpm the engine likes 13.8AFR for the best values.. leaner or richer will loose power
