Anyone who has already picked up an expert turbo should check with your dealership about a software bulletin. I picked mine up early November and have 1 ride on it so far. Last night I noticed 2 codes on it for "injectors shorted to ground" I called Martin to schedule brining it in for service. They called me back to tell me BRP has released a Bulletin and according to my serial number there is a required software update. it's getting fixed on Monday.
