6 wire motor running bipolar

I'm building a small CNC router and I have a question about 6 wire
steppers. I plan on using a Xylotex driver. I've been doing a lot of
research, as this is my first CNC project and I've come across a
conversion chart for unipolar and bipolar ratings. I'm looking at
some Vexta PK266-03B motors, rated at 3amps 2.3V unipolar. If what
I've read is correct, when running these on the xylotex board "end to
end", do the motors then actually draw 2.1 amps @ 3.22V? And do I see
a 40% increase in torque. Thanks.
