Weird Boost controller issue

[mRclARK1]

I'm using a GReddy Profec B spec II...it's working fine as far as controlling boost goes. The odd thing is the control unit won't read over + or - 9.9 PSI of boost or vacuum. It just stops reading there. I have a seperate boost gauge and it reads up to 12-13 PSI of boost at times; while my BC is stuck at 9.9 PSI.

My performance isn't being affected that I've noticed. So it's not a huge problem. It's just weird/annoying. Any ideas or suggestions? Thanks in advance.

ohhh thats scary, thats good that you have another gauge to go off of. idk its prob defective.

try rechecking the sources that u are getting the boost reading too

idk its prob defective.

That's what I'm thinking...maybe the display is just not working, because it seems to be controlling boost just fine.

I'll try rechecking the sources I'm reading from (intake manifold and IC piping)...maybe the connections are bad?
