Xyphoid, it's all really confusing and ultimately I think the best thing to do would be to call Crows and ask outright what's what. As far as I know, the cam I got (22825) is that one they talk about - but I didn't think cams were compatible between AU and the earlier models - so that title they've used is confusing. Also, the switching intake setup on the EF/EL etc. makes a huge difference to the way the engine behaves - so it seems odd to develop a cam using an EF "mule" which then is touted as suitable for EA-ED as well. I personally think that the lack of high rpm short path switching is the reason that cam fell flat in my ED - it definitely felt healthier in the EFXR6 head with EF manifold, but I felt the EFXR6 cam still edged it. The other odd thing is people talking about "stage 2 for EFXR6" and Crows site talking as if that original grind was stage 2 with a stage 3 comming soon - ????? Like I say, a call to them might be the only answer - sorry I can't help more with that.
