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!

the standard turbo will crap its self at 18 psi after a few boost spikes to that... atleast my stock turbo died after 3 or 4 times of hitting fuel cut.
so you have a full exhaust system 3" from the turbo all the way back... turbos clocked downwards i assume... your running a front mount air to air intercooler? how is the boost being regulated? by the stock turbo wastegate or have you just got the vacum line disconnected from the turbo? take a picture of your turbo? there should be 2 tubes ontop of the factory wastegate... where do those go. |

Yeah it's clocked downward and I am running a front mount intercooler. Right now I don't have a boost controller so it must be regulated from the wastegate. I'll look to see if the vac lines are hooked up to it. I bought this car not too long ago, so I'm still trying to figure out what the previous owner had done to it and what I need to fix / improve. Thanks for all your help.
