I have a 98 a4 with giac, and forge 007 and which way if the best way to hold the boost? I hear that some people keep it like stock and other will reverse it. Im also having problems with boost falling off to about 8psi at redline. just need some help.

 

looks like you need a different spring man

 

since its a piston design it will work the exactly the same either way, either your turbo is running out of breath... or you should upgrade the n75 valve

 

I have the yellow spring in, and i have the n75 j valve on it now...i found i huge line under my intake manifold that was busted. Do you think it could be my problem with my boost?

 

or you have some boost leaks your need to take care of

 

I have checked every where and nothing...what do you think that huge line under the intake manifold that looks like it goes to the block? big problem?

 

fix it, and you will know

 

Yea that could very well be your problem man... fix that and let us know what happens

 

is the tear in a hose? if so it could be a boost leak, which would explain your problem with boost

 

ok thanks! Did your boost hold throughout redline?
