Red, Bean told me that dyno # was before his tune/gutted header/slip-ons. He said dyno time down there is just too expensive.
I have a new 14 as well, and it seems you and I are on the same quest. If I might offer a word of advice...don't get in too much of a hurry, and read, read, read. There are at least two other ZX-14 sites, and I've yet to exhaust all the reading I can do here. You will find that a certain number of people tend to dominate the postings on any one site, so to get the best overall/most rounded viewpoints, I've found it important to accumulate as much info as possible from as many sources as I can find. Opinions abound...
In terms of Jeffo's tunes (F.A.I.C.), use the search function here to start. There is one particular thread that is quite long, and you'll have to wade through, well, a lot of crap before you can glean anything that you might deem worthwhile. Lots of opposing views, and some emotions run high. Spoiler: there are a couple of people here who are very unhappy with the results from his tune, and many who are more than pleased with how their bikes runs with his tune. I've read over and over that the best way to communicate with/learn about jeffo's approach is to call him. There is not much info on his site regarding his tunes, and it's common knowledge that he prefers phone communication to email.
Something I have read on another site, but have not really seen discussed here, is that tune files get shared quite a bit. Those who develop them originally are not happy about that, of course, but it also has been implied that even some of those who may be selling "canned" tunes under their own name have copied/modified tunes from other sources. I wouldn't know; just reporting what's been suggested elsewhere. I can certainly see how that could happen. On another site, I've seen members offering to share their files with others. They make the point of their "ownership" of the tune, whether it be custom or canned, as they paid for it. (Until such time that tuners are able to patent/copyright/include security for their tunes, it seems that practice will continue) Some tunes, such as Brocks, cannot be bought "stand alone"; only with the purchase of his bolt-on parts like his pipes.
There are some racers here with proven results, and one who is particularly generous in sharing his experience is slowninja. Look for his thread on his findings as to what works and what doesn't. He offers a kind of "menu" from which you might select; I've decided that a good pipe, 47 mm throttle bodies and a custom tune is worth saving my pennies for, and his thread was very useful to me in that conclusion.
One last thing I'll offer here because your original question is about taking the flies out..It's my understanding that on the 2008+ bikes, the flies are unrestricted in 4th, 5th, and 6th gears. I took a very fast ride yesterday, and believe this to be true; I found the power to be more linear and immediate in those gears at all rpms. Most folks say that they feel that the slight limitations the computer imposes on the flies opening in the lower gears gives a smoother throttle response. I'm not sure I agree. This bike necessitates judicial throttle control on exit of tight corners, for sure, but, I've found the flies opening can be somewhat abrupt/glitchy in those conditions, upsetting my line. I seem to be somewhat alone in that observation so far as what I've read here, so see what you think on your own bike.
Good luck with your new ride..
