Should also mention the Injectors are different, both use 45mm throttle bodies but the 750 uses early type green injectors that flow 270cc/min where as the 620 uses the later Pico Brown Band injectors that flow 330cc/min.
Both use the same Throttle Position Switch and 3-Bar fuel pressure regulator.
Fitting a PC3 USB to either will allow you to fuel Map each cylinder independantly
