[LX5liter]

I was told the f-cam was a decent blower cam by the shop that sold it to me . Oh well its in there now. Has anyone solved the mystery as to why this cam has these characteristics? Is there anyway to fix or at least lessen the problem?
I run the best gas that I can get around this town and as far as the cc's on the heads...I don't have a clue. I should've checked them before I put them on.
