Since I put on the mp2 I have been thinking of going from a 75mm to 85mm throttle body. From a 76mm mass air to ?? I plan to overdrive the blower another 5% from 15 to 20% I dont mind spending money if i will see some gains but am tired of spending it to find out it was a waste of time and money. If anyone has done this upgrade and can give me some imput please chime in.
