Thinking there are prob Thousands and thousands of people across the USA running SE 255's and VERY few have a ping issue that can't/hasn't been tuned out..
IMO U shouldn't need to add to Ur fuel to try to get it to stop pinging.
Thinking it is 99% tuning issue that as above said, FM-Jamie should be able to help Ya.
let us know when U get her running the way she should be...
I still think it's your tuner. 98 octane fuel? 93 is about the best we find here unless you go to race fuel. If indeed you have 98 fuel and it still pings take the auto tune crap off and dial some fuel and cut a little timing. what is your target AFR? I have to say that you are looking for the magic bullet to fix this and you are not telling all the facts needed to diag this problem. Or just call Jamie at fuel moto and let him walk you through it. Thats his tuner he markets. He knows more about them than most.
I called jamie. My target afr as I already stated is 13 through where it is pining. As for the fuel, yes, my mistake, it is 93 and then running octane boost on top of that. I guess not 100% sure what it works out to. The ping was there before the pcv, and before the auto tune. Timing is cut as much as I can without having the bike miss and run like crap. I really don't know what other info I can add... I'm running quiet baffles in my pipes, so there should be enough back pressure...

I agree. I really don't have some crazy mix of parts here... I have a very everyday setup and although i do, i shouldn't have to run octane boost or anything. Even with the HD 103 flash I have the very same ping so it is not a pcv issue. The bike actually has been running great with the original pcv/ auto-tune setup I had, but since I've been adding fuel and cutting timing the bike seems to be getting lazier, with no improvements on the ping. Anyone ever add timing and get rid of a ping?? Probably not.
Adding timing will only make it worse. Did you change the plugs to a colder one? Thats one thing to try. You shouldn't need octane boost. It would be nice to know what the ccp is, I have 197 and don't have a ping, but then again I have a SERT tuner. Yes you had the concern before but the tuner is not helping you with this. I'm not sure how the PCV tables are written. Not sure if it's throttle postion or map on how it adjusts the tables.I would try to tune it out without the auto tune as that could be screwing it up and adjusting it back to what you started with. 13.0 is very rich I wonder if you have carbon buidup in the cyls and that could cause it too. You are way richer than I am. I'd go to around 13.8 13.9 and go from there

My tables go by TP/RPM for both fuel and timing. I just set my timing back a little more through 60% throttle, and a few spots even earlier then that. I also just leaned it up a little because I did find it was running pretty rich. I didn't test drive it yet because I'm tired, and it's pouring rain.
I did pull a plug (good color) and took a look at what I could. There was carbon on it, but could also see lots of bare spots too. I didn't see any marks from detonation, but it was hard to get a real good look at it. I'll hit it with seafoam before my next ride. Dealer told me it could be a intake leak, but I've driven through a lot of heavy rain and it always ran like a champ, normally that would cause problems with a intake leak, right?
Sorry guys, I appreciate the help you're all giving me, just so f*%^ing frustrated. I have what should be a pretty mild and safe build, spent the money for a decent tuner with auto-tune, and just can't get anywhere on this problem. I spent to much money on this thing and don't want to be tearing the engine to pieces. Maybe I'll say f*%^ it and run her till I put a hole through the piston and then do a whole new build.

197 and no ping? That's pretty dang good. Until jlasoftail screws a pressure gauge into the spark plug holes and checks his cold cranking pressure there's not much anyone can help him with.

OK, OK... where do I get one? I don't have time to take it to the dealer for a few weeks, so is this a "any auto parts store" type thing? Sry, I know that's a dumb question...

This isn't going to work good with auto compression release, is it? maybe just pull that fuse?
Make sure the ignition and fuel pump fuses are also pulled. Some people say crank it over 8 times but I have only seen it done where the cylinder was cranked over 3 times.
