I would need the logs off a o2 equiped bike with the majority of the AFR table set to 14.6
Just run it on the dyno as if you are just calmly driving down the road. Better yet, a data log off a bike driving on the streets.

I don't have any 50% tuned bikes in my portfolio...sorry
I'm not fighting anything except the fact of some pipes, higher compression, larger cam overlaps, and larger throttle bodys take longer to dial in...in other words more edits have to be made in some areas which require making more runs to see the change that was made from the last edit. An inexperienced tuner will make more runs than a seasoned tuner because he is learning the program, simple edit mistakes which requires more edits, etc. I can normally get a tune done now with two edits on each cylinder which amounts to about 60 runs or so to synchronize the VE tables. No battle here just taking the necessary steps to do the job correctly.
