shifting issue

I'm having trouble trying to get the trans to shift from 2nd to 3rd under wot and if you are in the gas hard. It shifts normal, pulls in 3rd as well (locked the car in 3rd), even shifts into 3rd around 50% throttle.

I've tried lowering the shift point vs vss and still get the same result. I have a log from efilive with the following pids if it would help.

Any suggestions?
