So here are a couple of pulls I made yesterday. The first one I get 3 deg. KR at the same time as a slight spike in RPM. Actual A/F is slightly richer than target A/F. The second no KR. I'm new to tuning with FAST so I'm looking for help in figuring out what's happening. FP rises 1-1 with boost.

That's what I was thinking since the wheels did break. Would that be Knock or false knock then?

False = wheel spin

The way to check for knock is to find a long safe road and slowly lay into it in 3rd without a downshift happening. If you get knock then I would say it is real.

Or use a dyno.
