Are we Leaned out, or Rich ??,took look at my Ti-Yosh Can today (the inside) and it was pretty Black & sooty,Tells me I'm running rich. I'm not much of a wrench, but I assume rich is better than lean, otherwise running Lean your too Hot and will Prob. blow your Engine.
My wrench here in NJ did a Re-Map a few months ago when he put my Pipe on, Yosh Box, not sure of the Settings.

Lean or Rich ??

Check your spark Plugs for color,should be brownish,if black you're running rich,if white you're running lean.I rather be running rich than lean.Most setting after new pipes install is +5,+5,+5,then from there you can adjust for better performance.Good Luck
