I just make my first important altitud change since i instaled the boos meter, and i can see up to 1.5 psi more on lower altitude and it tapers much more in high altitude.

Has anyone experienced these?
How can i go aroud it, since where i live its really high 1400 mts.

 

thats just the way it works..air volume and density at higher altitudes. Less air the higher you go.
