As far as rod knock, I believe that would be occuring throughout all rpms as well as at idle. It only makes this noise under the previously mentioned conditions, this is boost specific as best I can tell. 
Would a wastgate make any noises if it were going bad? |
This bothered me, running 92 octane and a bottle of octane booster does not even out at around 100-104 octane. A bottle of octane booster only adds additional points so if you're running 92 octane + octane booster = 92.5 or something like that only.
Now if you went half tank of 92 and half tank of C16 then you're looking at high 90s octane.
