Help 4L60E TUNING Shift Firmness

I need help on making my shifts harder.
Long story short,I built the trans and it had troubles. I blamed it on the shift kit so I removed it.
I'm using JET DST but as far as I tell the parameters are the same as CAT2.
The trans is built and just want my tire chirps back....
