Just started to tune my first turbo setup.

Sorry if it's a noob question but it's worrying me.
At idle, table ignition marks zero and actual marks 2.5. Looking at the datalog I noticed that difference increases for about plus 5.5 degrees at 5000RM.

Is there any option in Preferences that adds ignition to the table by RPM or other variable?
Ignition Dwell has something to do with this difference?

Or should I uncheck Ignition Adjustments at Main Settings?
Thanks for all tips and tricks.
Cheers!
