If the model is 330 x 330 on the build plate in Cura then that is the size it will slice. To my knowledge there is no further scaling of a model within Cura to generate the gcode. Do you happen to be using Octoprint? Do you have a post-processing plugin active?
If you open the gcode file with a text editor, at the beginning of the file Cura inserts comments on the model size plus the room taken up by a skirt/brim/raft. If you subtract MinX from MaxX and MinY from MaxY you will get the amount of floor space that the model takes up.
This is from a 25 x 25 cube sliced with no skirt or brim:
Because there is no skirt or brim: MaxX - MinX + LineWidth = ModelSize so 127.3 - 102.7 = 24.6 + .4 line width = 25. If it was sliced with a 10mm brim the math would come out to 45.
Post-processing a Gcode file to mirror it is pretty easy, but scaling a gcode file is not.

Cura 5.7 is here and it brings a handy new workflow improvement when using Thingiverse and Cura together, as well as additional capabilities for Method series printers, and a powerful way of sharing print settings using new printer-agnostic project files! Read on to find out about all of these improvements and more.
S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
(Sorry, was out of office when this released)
This update is for...
All UltiMaker S series
New features
Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.

This is from a 25 x 25 cube sliced with no skirt or brim:
;MINX:102.7
;MINY:102.7
;MINZ:0.2
;MAXX:127.3
;MAXY:127.3
;MAXZ:25
