I just did a CAI and pulley swap on my car. Car is running well, but the factory boost gauge doesn't seem to work. Is there any nearby wiring that could have been messed with?? I've checked and nothing is loose/unhooked... Any suggestions?
Did you load a new tune that includes your mods? If not, that's the problem. The factory boost gauge doesn't display actual boost. It displays a calculated number based on multiple parameters. If it doesn't know about your changes, it calculates based on faulty data and gives a faulty reading. If you did, in fact, load an upgraded tune, it may or may not be the cause.
I did upload a safe tune I got, but this does very accurately describe why my gauge isn't working. I plan on getting a solid tune from Lund so I'll have to deal with it for just a little bit. Thanks Steve!
