My reasoning for pipiing the mbc to the inlet, was to stop boost spiking so much. A google search revealed it to stabilise when the turbo comes on boost....?
The reason this is done is that there will be a pressure difference between the compressor housing and the inlet manifold (things like your IC will cause a drop), so if your actuator is set to open at 10psi for example you may only be seeing 7psi (3psi loss through IC) at your manifold, where as if you pipe the actuator to the manifold then it will not open until your actually making 10psi at the inlet (as showing on your boost gauge).
