Knocksum of 7
While going through some logs I noticed that I would occasionally get a high number of knock. It usually varies from 4-7. This is after I installed an AMS boost pill along with the 2012 USDM Boost pill GST basemap.
Here is a link to the portion of the log that shows the knock: https://docs.google.com/spreadsheet/...2o4RVQxbWJsMUE . Should I be worrying about this?

No, you shouldn't worry about this, because load is < 80 and rpm < 2000. Cylinder pressures are low. This kind of knock is very common for our engines. Here's a pretty good posting on the subject...

I know a couple of people who have gone all OCD trying to eliminate this... but seeing as it happens on 100% FACTORY tune too, it's not something to lose sleep over.
