How To: Knock Desensitizing for Forged Engines
In my experience, you will want to adjust the "Knock Threshold Weighting Factor" tables as well as the "Knock Threshold Level Final Limit (Max)" value. For the 2011 WRX, the former tables are Per Cylinder, so there are four. Here is the stock "Knock Threshold Weighting Factor" for Cylinder #1:
