The only way you'll truly know is to try it. Ergos and suspension don't matter, if his bike is set up engine - wise the same as yours it's apples to apples as far as the ECU is concerned. BTW... both will need the same part number or you'll get a CEL for emission controls.
Has he tried riding your bike, or is this an issue of the setups being so different he would be overwhelmed with all the differences and not be able to concentrate on the smoothness and throttle control afforded by the flash?
