What’s the length of your Bowden and what are your retract settings?

The bowden length is about 55cm, 6mm retract with 80mm/s and 20mm/s unretract. I used the experimental slic3r from https://github.com/llluis/Slic3r
The extruder Motor is a Nema23 http://www.thingiverse.com/thing:321948

And I forgot to mention it’s made of ABS (glow in the Dark 1.75mm)
