Jun are also very good cams kinda expensive but much better than aem or dc sports. I personally do not like the DC sports or the Aem cams. If your looking for real power go with Jun, Toda, or Spoon in that order. If you dont believe me just look at these dyno charts
Dyno Charts for JUN Toda and ITR cams! The ITR is a very good cam probely a little better then aem or dc sports cam and look at the results.
