I know that the differences between the two motors are compression, timing and ITB's (individual throttle bodies) but do you think I'd gain anything/hurt anything by running FX140 ECU/ITB's on the VX motors?

With less compression in the VX I would thing I should be able to get away with running the FX timing (I assume timing advance is controlled by ecu) and with the ITB's more air should provide a little boost in top end and throttle response... right???
