You can set the idle speed settings with your SCT, and see what they are set at, too.
Sounds to me like you have something going wrong somewhere though, perhaps even a vacuum hose disconnected.
Hook up your SCT and do some datalogging on values including throttle position, air flow, long term fuel trims, rpms, and maybe a few others.
If your long-term fuel trims are like +8 or more, then you have a nasty vacuum leak and that will affect idling (been there!).
Maybe there's other ideas, too.

I search for any data errors but nothing.
After loading tune it asks if you want to make any changes, i always click NO.
Thanks
