There are a couple of options, like
@Evil Mitch said a dyno (with a good operator) will give the best results. There are also a couple of people on the forum that write good tunes (but you never know how the actual A/F ratio is). PCV with AT works well too. A couple of people like the Dobek unit. I haven't personally used one but it does sound good, having the ability to switch from power to economy on the fly.
If you do go with the 210 Carpenter Rocket, and change to Carpenter's pipe and the K&N 4040 filters (I have no idea what filters are on it now). You can call Carpenter to find out about sending them your ECU to flash with the right tune for that setup.
