Since you have the power commander, I would also recommend you getting the 50mm throttle body that the 09 Renegade has as well as the 09 intake and filter. The guys that have the 07-08 Renegades that have done this say that it helps it tremendously.
Then you could do some MrRPM cams and pistons to really wake it up.
What clutch kit do you have?
I am running and airdam clutch setup with modifiued dalton weights, stock secondary spring and a white EPI primary spring in my 09 800-X.
I've been pondering the STM secondary clutch from
Supreme Tool but everyone says once you do that, you will WANT to get the STM primary since the stock primary isn't very tunable compared to the tunability of the STM pieces.
I've attached pics of the secondary and the 6 weight primary they sell.
