Since it's the same engine from the CBR bikes, I would start looking there. There will be some difference thou, since Honda re-tweaked the engine when they put it in the 2017 Rebel. So the engine allready has better "oomph" as you call it, than the CBR bikes.
Exactly what Honda did to achieve this I do not know. Could look into that, see if it's possible to gain even more from whatever they did.
Besides this, I do not know. The Rebel ain't meant to win any street races, so can't really see the need for anymore "oomph", but to each their own ofc.
