I thnk the PCV is probably not worth the cost and effort to install for your setup unless there is some reason you are not happy with the canned map. Your money would be better spent on a custom tune IMHO. I have an 09 with a full Yoshi R-77 just installed. I have a PCV with Autotune. I bought the Autotune over a year ago and never used it! Bike ran perfectly on the custom map.
If you are set on new electronics, I would look at the new ECU programmer with autotune Boost by Smith has, that looks to be a great setup. It's a little more than the Dynojet stuff but looks to work more seamlessly. Remember with the Autotune you have to constantly fiddle with the PCV to get any improvements.
Just my opinion
Actually I believe the ECU harness is cheaper than the PCV once you add the auto tune module...keep in mind you are dealing with two units when you get the PCV and autotune.
I do like the autotune and have had good readings with it but I do not have the numbers that you are looking for on paper to compare. My ECU is also flashed for other reasons, but my normal tuning method is through the Autotune from dynojet.
The ECU flash IMO gives you a much wider range of options for the $$$, it all depends on what you want to do with it and how much you really want to get into tuning yourself.
As far as fiddling with the PCV, you would have to do that with any program even the ECU flash if you are attempting to keep a constant tune yourself.
If just tuning for a slip on can, like said before you may just be better off getting a custom tune and be done with it.
PS: One other thing,,,I have no idea why they only list the PCV and autotune for the '09 and up. They are the same unit and work fine on the '08. They will even tell you it will work but they don't support it...haven't figured that out yet.
