Boost gauge issue.

So I've had my APR boost gauge for a while now and I have always felt like it reads a bit to high. A buddy and I did some loggs the other night and his ecuX was reading out 22.6psi, but my gauge was reading about 26.5.. Is this a common thing, or am I the only person having this issue?

Which line did you tap into?

I cant remember the name of the hose, but is the one coming off the manifold. I know it was the right one.

22.6 is the max your that MAP sensor can read. So you are probably running what the boost gauge says, but the MAP and ecux can only read boost up to 22.6.

Shit, that was the one answer that I was afraid of hearing. Ok so its back to the drawing board with my tune.

Ok so I started looking at some old logs and one of them reads 22.94psi. If the map sensor only reads up to 22.6psi, and ecux is capped at that psi as well, how could it have read 22.94psi?
