My boost gauge isn't going past 0 in 1st or 2nd gear then increases very quickly in 3rd and 4th. I also notice that once the gauge starts reading boost in third I can then go back into second and it reads it when I'm driving more aggresively. It seems like I'm making boost in those lower gears because my bov is hissing at me
 Any thoughts? I currently have the gauge hooked up to the vac line that goes to my bov. I tried moving it to the line that is suggested in the 3sgte maintance sticky but it doesn't seem to be reading correctly either. When it is hooked into this line it only goes -7 and still doesn't push past 0 in 1st and 2nd. Any help would be greatly appreciated. Thanks!

In 3rd and 4th it shoots up to around 18psi when I'm driving hard...seems like it cuts off there. It seems like after 2nd gear everything works ok. The gauge just isn't reading past 0 in 1st and 2nd. Right now my exhaust is straight 3in pipe with no cat and a 3in dp. I'm working on getting a muffler and resonator on there
As far as running a boost controller...I don't have one yet. I'm thinking about getting the greddy profec B.
