How to make turbo run from lower RPM

Hey so mo question is how to make turbo run from lower RPM ?

Because after stage 1 i get power only from 2200~2300 RPM.
Its going from slow slow to instant fast

What map should be edited to make that boost from 1800 RPM not from 2200~2300 RPM.

try adjusting n75 map if specified boost doesnt follow actual, it can also be used to reduce turbo lag but be carefull of overshooting after, need to be done with logging

I found me N75 usable map.
And i can't understand how changing this map will make me turbo work from 1600~1700 RPM not from 2200~2300 RPM
Because as i can see its have 90% on low revs and its decreasing as revs increases.

First Line Horizontal in selection = -2.2%
All other lines in selection = -4%
