about the itr cams, which is cheaper...hmm. Also, I stand corrected, hondata does support 1000cc injectors, the reason that the person that I know opted for aem is the flexibility that aem has since he has free dyno time. It was only a couple hundred more for the ems so he went for it, just gotta get it tuned in now. I never said that ITR cams will not make over 600 whp on boost, I just mentioned that gs-r's will too, and they are a cheaper alternative.
