52mm Throttle body best on which .VVC or MPi

Assuming that one can be obtained at reasonable cost which of the F's would benefit the most from having the 52mm throttle body fitted?



VVC or the Mpi?



The VVC has a K7N open cone filter fitted.



The Mpi is having a TF 135 air fitler box fitted and I hope a perfomance panel filter.



Currently the VVC has a de-wedged/modified alloy 48mm body whilst the Mpi is running it's standard plymer one.
