Welcome and thank you for allowing me to assist you! This blue smoke is caused by worn valve stem seals. I see this a lot on the 2.5 Mitsubishi built V6 engines when they get up in mileage. Have the valve seals replaced and this will take care of this blue smoke issue. It is not a MAP sensor or fuel pressure regulator.
I hope this information helps and let me know if you need further assistance with this.
