That seems entirely too hot. IIRC my replacement t-stat opens about 90C and keeps the coolant about that temp. In my case when mine was stuck 'sorta open' my coolant temp never got to even 80C if the ambient temp was below about 40F, and not even 60C if ambient was below freezing.
Do you have an IR thermometer etc to get a reality check on your coolant temp (measure the temp of the hose), i'm wondering if your temp sensor is off (way off) and '109' actually is 90. Otherwise, it would seem the replacement is 'stuck shut' at least opening way too late.
