did some 3rd gear runs today and had some knock sums show up btn 3300rpm and 4400rpm #'s like -178 to -497. i am running a high boost tune, is this safe territory? please advise. Please see datalog #7 and 8

Not had chance to look at your logs, but if you are not going more negative than -768 at which I set the default for the boost gauge to flash then i believe that is safe on most setups.
