Yes it does, however, do note that there are limitation to your hot end and extruder too how fast your extruder can push and how fast your hot end can melt the plastic.
The parameters you used during slicing is the default means at 1 or 100% speed in FR (feed/flow rate?) on the lcd panel, lower means slower and vice versa.
Frankly, I only used this twice, increasing the speed, didn't see any defects, I only tried it on normal cubes
