Look at your log data and see at what rpm ranges you are getting knock if you are getting more than 6 ST knock at any rpm range, retard your timing in 2 degree intervals in that RPM range till you see ST Knock drop to 6 or below also LT knock is bad, 2 LT knock or less is tolerable.
If at all possible you could run 91 oct or higher this will also reduce your knock but since this is the 87 tune try the above
But remember doing your own tuning is not advised i would look into getting tunes from HEMIFEVERTUNING.com Sean does great tunes that are safe.
