Boonie Box Fuel Numbers for a 2014 with RK Tek rev1 Drop-in?

I'm just looking to see if anyone is willing to share some Boonie Box fuel numbers for a 2014 800 Pro with an RK Tek rev1 (13.5:1 Head) Drop in....5-8000 ft? Thanks for the help!!
 
Depends on your elevation it seems... Above 7000' my experience is Kelsey's #s are way low on my sled (13) and it liked about 10% in the mid and 12% on top. And below 6500' it seemed good with 6% in the mid and 4% on top... I am curious though when I get back into some lower elevation what it will do with more fuel cause I never tried anything higher than Kelsey recommended until It was running like a turd in higher elevations. After I started adding fuel it was running about the same clutch weight up high as it was lower.
 
HRT did you ever find any numbers for this? I know 14s and 13s are different mapping.

Nothing yet for my elevations. I got some numbers from tinkerjohnson, but he is riding much higher elevations. It's an extremely lengthy process tuning properly without an AF gauge...so I think I may spring for one if no one can help me out. Kelsey's baseline numbers appear to be way off IMO.
