I saw this being tried at bexley Motorworks on nigel's own car. Car was a 520i 12V.

First dyno gave 129 bhp with standard setup, dyno with 325i inlet and TB gave 1 bhp less. Engine was running much leaner though. Maybe with a remap it could give some useful gains.

I know that just using the throttle body on its own makes a difference though.
