Just ordered a PC V
I have one with auto tune and my 'hot' ride is nice and cool - and fast. You'll love the laptop monitoring feature.
Search iClick's posts for great write-ups.
Did you order auto tune?
What's "Auto Tune"
It works with the PC-V specifically. It replaces your stock narrow band O2 sensors with new wide band sensors and it allows the PC-V to 'see' the air to fuel mixture ratios (AFR) as the bike runs throughout all rpm ranges - the stocker is only good for a selective range of rpm. Thus narrow band/wide band.
You basically have a map table with the target AFRs for incremented rpms at incremented throttle positions. This system compares what the bike is 'really' doing and modifies the individual setting needed to achieve the proper AFR results (Auto-Tuning) on the fly.
Now imaging you magically just changes cam profiles - no problem, the AT would see the on the fly AFR change and immediately modify the (trim) settings. Change your exhaust - same thing.
Without AT someone has to manually create the base map to operate your bike. Jamie is great and has some known recipes for exact exhaust, intake, displacement set-ups. These are based upon his dyno testing on these set-ups. So slight variances in each bike are not accomidated. But, these are way better than nothing.
The other way to create the maps is to have someone dyno your bike and thrash the crap out of it for two to four hours and hope their equipment is calibrated and they know what their doing to achieve the AFR results you want. Guess what - change so much as the air cleaner and your bike back up for another round of thrashing to reset the map. Oh, yeah - another $350 for the dyno work, please.
In the end, for me, I don't care what the dyno numbers say. I'm not in the d!ck swingers club. My rearend will tell me when I'm happy with the performance of my bike. I love the great gains I have in PC-V AT set-up, but I have some exhaust improvements and cams (SE255) I think will get me to my own power nirvana. If I'm not satisfied - I'll go to 103" or 107". My PC-V AT will be right there the whole time with zero more $$ invested in injection management/tuning.

Research iClick's posts on this topic - they are great threads and very techincally oriented if you thirst for more info.
