Hey all,

Just as the title says, the boost gauge is reading 0 at all times. I feel the turbo kick in, but at the same time... i feel that it is sometimes lacking in the "umph" that i expect. is it more of a turbo problem or simply a gauge problem? if so, i'd prefer to check the gauge before removing the intake... any suggestions on what else it could be? Thanks in advance.

 

gauge is probably toast .. havent you learned yet not to trust mazda electronics lol ... hook up an external boost gauge and check for vacuum leaks

 

my car does that too, but it comes and goes. but when the gauge does work i feel a difference in power for sure.

 

i have the same problem , i just hit the plastic and it works again.. idk why but its like it gets stuck

 

that means ur pressure sensor isnt hooked up

 

loose connection....
