Looking at the CCD Inspector plots it is indicating your collimation is good but you have tilt. Tilt and collimation are 2 different concepts.
So the source of the tilt would appear to be the focuser as it appears the tilt is always towards the bottom of the image (focuser leaning downwards?).
Can you feel any play in the focuser with the camera installed.
The 2 crosses in the middle of the CCDI plot show collimation. They seem perfectly aligned.
So it would appear that if you played with the lens cell adjustments it would only make things worse. Best to adjust the focuser first.
I recommend you post this on the Yahoo Tak Uncensored site and have Art or Fred comment on it. They are the experts on Taks and are super knowledgeable and helpful.
Or call Art or Fred at Texas Nautical (in Texas USA).
Greg.
