Can't set Retraction speed over 40mms

[You_N_Me 0]

I just did some calibration and retraction testing using custom gcode and ended up with a retraction speed of 45mms and liked the way it looked compared to 40, when I tried putting 45 into cura it went red and said I couldn't do that.

 

Why and how can I get it to do what I want?

Your printer definition file has limited your retraction speed ("machine_max_feedrate_e").  If you have the Printer Settings plugin loaded you can change the max feedrate there.  It has no effect on M203 in the printer (where the max feedrates are stored), but it will allow you to enter higher numbers in the "Travel / Retraction Speed" boxes.
