| I think there are a couple of different power stages with the amd unit, my friend had the one that was ment to bring it up to 115ish bhp (from 90) and was not a patch on the bluefin.
Having said that she had the middle one of three stages, think the highest is ment to be slighly over or the equivalent of a bluefin map.
For the money i would stay with your bluefin.
