You are still knocking a bit (-3 FBKC), but nothing as bad as you were. The thing that stood out to me was the weird timing curve. If you plot RPM vs. ignition timing it should be a nice smooth curve that hits it's lowest number around peak torque and slowly builds back up as you move into the higher RPM range. Yours seems to sort of bounce around a lot.
Yeah I did notice knock went down after a resecured the heat shield. I did hear some rattle. Other than that I'm still learning to read this things. What should I do? Should I try some octane booster? Maybe a reflash? I bought my ap used so who knows if the maps could have been touched... idk
