Cool great job 
Thank you for the G-code feedback tip it will help others
Ya try to work without tpu supports if you can with your part designs.
Did you use the 95A retraction speed @100 mm/s and 300 travel speed setting ?
The supports are @ 30 mm/s for pva plus I also do other tricks with painter tape as interface support layers to get clean bottom tpu layers.
The 95A TPU will run @ higher speeds
