I purchased this gauge for use in MSFS with my Saittek Panels (I have 12) and SPAD Next.
When I fly more complex options (then my usual 172) on the Sim, I use this panel.
It accurately displays my manifold pressure. A quick glance is all it takes so I can adjust as needed.
I highly recommend this gauge to add to your sim.
