@Sonofswin, removing the snorkel will lean it out just a tad. It would be a good starting place with the yoshi map. You could remove the snorkel and go from there.

A dyno run, even some place that doesn't do mapping, will get you a good AFR vs. RPM read-out that you can then use to adjust your numbers in the PowerCommander map accordingly. I would say within 3 dyno runs like that, you should be able to get it mapped pretty well on your own, assuming you're ok with the software that the PC comes with.

Download Yoshi map.
Test ride to see if you think it needs changed at all.
remove snorkel.
test ride to see how if that makes it better or worse and if the map needs to be changed at all.
Base run.
adjust the map a little according to the AFR vs RPM data.
Run 2.
Adjust the map a little more according to the AFR vs RPM data.
Run 3.
Hopefully it's right by then. If not, you should have it close enough that it's ride-able and nearly perfect.

Just make sure that you have the intake/exhaust setup that you want before you start doing dyno runs so that you don't have to start all over if you decide to make a change

EDIT: if you install the Yoshi map and pull the snorkel, and decide that you like the way it feels, getting a base run on the dyno is still a really good idea to be sure that you're within safe AFR ratios throughout the RPM's.
