do i need to retune after MAP SENSOR?

..im a noob still with my kpro and tuning and such...

anwyays..
ive been getting boost cut lately..
and its been confirmed by me datalogging and looking over the graph...

i have a stock MAP sensor and it hits boost cut at 10.0 psi.. not leaning out or anything..

I was wonder if i can just plug and play an upgraded MAP sensor without tuning again...


thanks in advance..
