Would upgrading to the MPX from the MPIII show big gains? Since its on sale I'm thinking sell the MPIII that only has 1500 km's on it and buying the MPX while it's 1085.00 this month, plenum but no rotors I think. Or would the money be better spent on heads? Mine are stock but I have all the other goodies...missing some power it seems.
