New WRR Owner, question about Fuel Management

Hello all, relatively new 2016 WRR owner here, also first post. I have been doing quite a bit of reading about the FMF fuel mapper, and PCV also. I'm interested in adding a programmer, while keeping the stock exhaust (for now). I'm really looking to remove the stutter that the bike has stock whenever you open the throttle quickly. It makes it much harder to loft the front wheel, and it's always there it seems, at almost any rpm, however it's worse at lower rpm's. It acts like a carbed bike with too large of a leak jet, almost as if it's not getting enough fuel. I'd assume this is due to the conservative stock fueling. My question is, after some reading it seems the PCV has an accelerator pump feature. Do I need to get the PCV to get what I really want, also with the idea that i'll be adding an exhaust later, or should the FMF do the job? From reading I feel like the FMF is just the cheaper option, and might be less capable, but i'd like some other opinions.

The idea of having more knobs to turn, as far as fuel injection goes does not scare me at all. I've previously owned/raced a Cannondale MX quad and done many hours of FI/ignition tuning with those bikes.

Thanks!!

Adjust the follwing first, this did it for me:

Throttle cable free play set to almost no slop.
TPS adjustement
Change the CO number in the display.

Thers guides inhere for everything :)

What do you mean the CO number in the display? I'm not interested in adjusting the throttle cable, as that's not my issue. I'll look into adjusting the TPS. My friend also has a 2016 just like mine, actually both were bought within 4 days of each other, and both have the same issue.

I noticed a decent benefit just by unhooking the air box flapper, I left everything as stock just unhooked the linkage from the door. I got rid of most of that dead spot and jerky off idle, still not as good as a programmer.

Too loose a throttlecable wont be your main problem, but it can contribute.
If thats not the cse, just move on to the next thing.

As I said, guides are all over the forum. Heres a quick youtubevideo.
As far as I recall, theres a black wire that needs to be earthed in some countries, mine didnt.
