I would agree with the above comment r.e. value for money on the MPPK. I could see the argument for it before when you had to rip out the ECU to get a remap done, but with the OBD method now available the argument for the MPPK is largely redundant.
With the 30d I believe the turbo itself is the limiting factor in achieving more power, as opposed to the standard intercooler.
