Crunch,
First off, let me welcome you to the site, and invite you to go over to the new members area and introduce yourself and provide some pics of your new ride.
I went with the race tuner and SE air cleaner and they put a base map 84 in the ECM until I had my bike in for the 1k service and then had it dyno'd. $260, depending on where you live, is cheap for dyno. My shop charges $70/hr for the dyno and my bike was on it for 5 1/2 hours. But hold off getting the dyno done until you have the breakin mileage done. Most people wait until at least their 1K service. They will put the engine through it's paces and do full throttle, all the way to RPM cut-off, runs numerous times, so you want the engine to be "broken in". By putting the AC and SERT on they will bring the factory AFR down which, in turn, will allow that 110 to breathe freer and run cooler. There are other options, the Power Commander, or some others have gone with the Zipper's Thunder Maxx Auto Tune, which replaces your ECM and your narrowband O
2 sensors with wideband sensors. After having a base map installed to closely match the configuration you have, it will auto tune "on the fly" and eliminate the need for any dyno time. This unit is not cheap though (roughly $800), but is an alternative to what you're looking at to spend anyway. The big thing is to go with what your tuner feels comfortable with. But yes, it is worth getting that AFR down and open up the breathing so that engine can run the way it's designed to run. Hope this helps.
Cheers
