Hi all I was just wondering if anyone here has a dev 4 cam only installed and what does it feel like? I have had this cam installed in this current motor and must say that it is not performing as well as I expected.I actually installed it in my first engine and it was a very noticeable change.I would literally feel as thuough I was hit from behind when I tramped it at 60 kays. Now it goes good but not like before.Is it only me?
