So VD runs complete. I did 3 runs with vtec set at 3k and 3 runs with vtec set at 6k (all 45 degrees on high cam). I also, did one run with vtec at 3k with cam @ 40*. However, it was pretty obvious that 40 lost power mostly everywhere, as the AFR was richer. I also tried commanding 50, but the physical limitation of my car was around 46-47*, so I didn't think it was worth my time to even attempt to data log these runs. With these VD plots and reviewing my tune, I'm going to dial in my vtech around 4.4k.

However, back to the original question/issue - I'm still seeing pretty rich tip-in fuel. See the top photos, I set the curser at the same RPM. One is from my latest vtec of 4400 and the other is when I had vtec set at 6k. The fuel tables are exactly the same between the two files, I only changed the vtec set point.
