I see, thanks Scrmnvtwins and everyone else for the advice. To ya'lls point, I could just get a newer exhaust that has the O2 bungs already installed and then go from there right? If I got the O2 sensors and an exhaust that accepts them, how much of a hassle is it to get the O2 sensors to talk to the bike's computer? Do I just hook the sensors up to the PV and then use the autotuner?
Again, I appreciate ya'lls advice!

Your OEM ECM is not programmed to "talk" to O2 sensors. So the options there are varied in both expense and expertise needed.
IMHO... the simplest way (but cost a little money) to Auto Tune on your bike, with a PowerVision full service tuner, would be to also buy an Auto Tune Pro Module. The AT Pro Module will hook up to the PowerVision and give it the O2 sensor feedback to run an AT Pro Session. The Target Tune module may work too, in place of the AT Pro Kit, but I have little knowledge and no experience with the Target Tune module.
If you have a good, competent Dyno Tuner in your area, contact that shop and ask their advice.. about start up and/or riding before a tune, to include all the costs of them performing a dyno tune. I suspect that may be more cost effective than buying a new exhaust, a PV tuner, and an Auto Tune module. Plus you would end up with a really good tune...
Good luck... keep us posted on your decisions and your results

Thanks Hattitude. I was going to put a new exhaust on it anyway, so that may be the move. There's a shop near me that tunes bikes and I'm pretty sure on their website they mention using the PV so they may be very familiar with it. I can reach out to them and see what they think

You might want to talk to them before you buy a PowerVision tuner... Unless of course you just want the tuner...
I like buying tools.. If they are a PowerVision shop, they should be able to tune your bike with just a PV license.. It's Like $239 v $600.. If they do the license only, have them give you the license info. That license is for the BIKE, not the TUNING DEVICE. With that license, you will be able to have that bike tuned by anyone with a PV tuner. If you were to buy a PV tuner later on.. you could marry it to another bike, and then tune this bike with that license info added to your tuner.
If they are say, a TTS shop, if they are good, they can tune with either tuner.... But if you are just getting a license, go with the tuner your shop prefers... They can then give you their best tune...
Also, make sure the shop has a good reputation. I have met a few tuners (people) who have no business tuning a bike. Luckily they are the minority, but they are out there... And there are many really excellent tuners out there too ...
Good luck, keep us posted...

Ah, I figured that's what I had to do but I wasn't certain. Thanks for the tip!

If you go the Power Vision License path proposed by Hattitude, most of those guy have sniffers they shove up thru your tailpipe. If the muffler has a restriction they will ask to allow them to drill a small hole to push the sniffer into the muffler chamber.
Bottom line is if a tuning facility tunes with sniffers up the tailpipe you do not need to change exhaust to add 18mm bungs. The only reson you would want to add bungs is so you can tune with an AutoTune system.

Hello again y'all,
I haven't made any decisions yet, but I'm leaning towards getting a 2 into 1 with O2 ports and then getting either the powervision with the autotune kit or the thundermax with autotune. I just wanted to clarify some things about how these tuners work first.
Is it possible to install the tuner and use the O2 ports on the new exhaust to tune the bike, and then remove them and plug the ports after flashing the ECM? Or would I have them hooked in all the time?
