I've got a Greddy electronic boost gauge,
and a couple weeks ago i washed my engine, and ever since then the gauge started acting up
at first it didnt work at all, as in it wouldnt show the boost, then afterwards, it would show the boost being higher than it is, then it stopped again, and then it worked fine. and now it stopped again....
When it's not working, the warning light would keep flashing, anyone know exactly what that means?
i'm guessing the little cube with greddy printed on it could have gone bad?
What can I do?
