Gear adjustment when exactly changed? 451

Hey guys, on my 2007 84hp it was almost not possible to ride with Softouch, because it always turned up very late. My mother now has a completely new MHD of 08/2010 and it turns up really super early, sometimes almost a bit too early! Can someone tell me exactly from when this change was made? Or is it because Mama’s Smart is now an MHD and the Turbos still have the same vote? Are just looking for a Gee and that should have this new gear tuning, because finally you can use Softouch properly!!! Thanks already!!
