Aight I just noticed that my boost has been stoping at .5 and I thought it used to go atleast to one bar? I am a suby noob so be nice. It is a 05 wrx and I have had if for like 6 months. The only thing I have done to it is a spt intake other then that I havent touched anything. Any idea what is going on? It goes up to .5 then it starts to go down again....
My 06' WRX was running about 15 psi when it was stock that would be about 1.02 atm so I would say that either your gauge isnt connected correctly or isnt calibrated right anymore or you have a leak somewhere. I would check all the vaccum hoses around the TMIC and turbo. when the car idles what is the vaccum that you are reading on the gauge?
