Hrmm Joe. TD05 20G...thats the smaller exh wheel. 16G-20G being the intake wheel. Smaller than the TD06 wheel. Thats why the extreme clip on the exh wheel. Same wheel as the 16GTD05. Clipping makes lag but increases top end power. Decreases surface area on the wheel...but allows more to pass through. If you are un-sure just call RREExtreme or Beernuts(Bushcur). 7-10deg is probably for the TD06 wheel. Thats my half baked opinion anyway. I would go with the 15 degree clip though. Like this
