MAP Filtering

[Wallace7777]

I was adjusting my tune setting back to normal after VE Tuning and was comparing my previous settings for defaults and noticed something. My original file does not show Airflow>General> MAP Filtering to be on, it shows the setting to be "no filtering". However, as I was putting things back to normal from my last VE Tuning file, I see the MAP Filtering is now set to "Filter on IMTV Closed". I did not change this prior to starting VE tuning, that I remember, nor was it in my instructions I was following when setting up VE Tuning... not sure how this got turned on.

Couple of questions...
1. Could this have affected my VE tuning(fought VE and was just not very consistent)
2. Should it have been on in the first place
3. Did something else switch it on(the process) because none of my instructions previously told me to change this setting and don't remember doing that.
4. Should it be turned off now
5. Should I turn it off and go back and perform VE tuning again with this off?

Any help with this would be great!!!
