Playing with the timing will be my last resort. That dip is in all of my graphs. It seems that the more power I make, the more pronounced it becomes. Ricky Gadson's dyno graph did the same exact thing in his video where he installed the SC stage II on a 2016 H2 and poured in MR12. Additionally, he added timing with the Woolich flash.
Gadson had that pronounced dip with the stock exhaust. The bike he used in initial testing didn't show a dip in power up.
