2012 5.7 knock senor question

[sunny]

Do I raise or lower the values in Knock Threshold on this year to desensitize the knock sensors. I know you raise them on the 2015. Any input would be appreciated.

You raise the values to desensitize the sensors.

I've seen a few different methods.
1. multiply stock values by 1.20 - 1.25
2. multiply stock values by 1.50
3. multiply values by 1.50 if on boost and up to 2.00 if on boost with E85

I'd love to hear some input from more experienced users.
