Dennis knows a hell of a lot more about tunning than I ever will and I'm not trying to step on anyones feet here.
I have mine tuned at 0+5+10 with a dry shot and it runs great at low end with out the spray. I tried it at +5+5+10 and seemed to load up at low RPMs riding on the street.  Also +1/8  on the duration.
Each bike is different you'll just have to experiment.

Rice: Have you dynoed your bike with the dry shot? It might be a little lean even with the +10 on the yosh box. I ran mine like that to, but after having it dynoed last night with the PCII I think you might not be able to add enough fuel with the yosh box.

Just got back from the shop.went there for lunch.with just the muzzy pipe it made 163Hp.Then we ran the 0-5-5 map and got 166hp and the air fuel about 12.8
I figure I can sqeeze a few more out of it.

all depends on bike
many dont like any fuel in the low end
12.8 with-5 up topsounds like you did too many pulls in a row
which heats the pipes etc too much
will show up richer than the road
but hey whatever
never worked well when i tuned mine at the strip with those numbers
looked good on the dyno
but sucked ass on the track

They did do a bunch of runs.Here's a chart with the air fuel.Looks like it's mostly at 13 but you tell me.
