It will be easy then. If you see you are going leaner than 15/15.5 on cruise, enrich a bit. You need to be in the 12 or lower when booting it. Idle ... it can be lean, like 15-16-17.
Your timing and fueling maps depend on engine load, running a smaller turbo will just prevent from using the "highest" part of the maps, so timing wont be a problem. You could pull 2° if you feel the need to be safer.
