I know this has been done to death but I cant find a definative answer

Whats the boost level of a standard 04 STI Impreza?

I have just fitted a boost gauge and it reads about 0.8 to 0.9 bar? But I have read other people saying its 1.2 standard, others say 1.0.

Also my gauge vibrates when its under boost, it was cheap but wondering if anyone else had this problem?

Thanks

 

i would guess if cheap it not gonna be accurate i use mine as i estimate not a spot on way of knowing

 

make sure your gauge pod is secure with a screw and you can buy t pieces on ebay that stop vibration threw the vacuum hose and i think the stis are 1.1 bar not sure some1 on here will point you in right direction
