RE: Boost issue
But I am having all the same symptoms as the guy who put this post up inluding the loud whoosh noise when I punch it. Oh man I just want the damn thing fixed. I hear its a boost leak I hear its not. I'm just gonna have someone check everything I don't care anymore this is getting so annoying. Plus I want it working before all my parts get here.I just ordered an HFC, Borla catback, and a K04. I am getting the rest of my supporting mods today and tommorow but they wont do me a lot of good if I get kicked into limp mode.

As for you NuYorker, I doubt a boost leak is your problem since you are hitting limp mode which means you are over boosting. If you had a vac or boost leak you would definetly not be hitting limp mode since you probobaly wouldnt be able to make more than 10-12psi. Since your over boosting, I would check the plugs, ignition coils, and possibly the n75 because when they go bad they can cause fluctuations in boost.

yes I do, but it did it before I got the intake and it is on the drivers side. Its notmy intake or my DV. It is on the opposite side of the car but I still have pull. when I floor it you hear the motor then you hear psssssshhhhhhh and the car pulls hard if I hold it then the psssshhhhhh all of this sudden goes away and all yo can hear is the motor and intake and it accelerates like Sh*T!!!!

RE: Boost issue
found the culprit... theres a vac line dangling under the intake manifold... its short like maybe 6 or 7 inches... i have no idea what it connects to, as i'm new to turbo charged engines. anyone have any diagrams of the vac lines?

RE: Boost issue
weak power... good vac pressure, but i'm not boosting over 9-10psi. i just took another look at my lines, cuz i was def hearing the woosh / whistling noise. my L hose is fine, and i was looking under my intake mani and saw this vac line just staring at me... not connected to anything, i tried to quickly look for where it might go (as the engine was still hot) bc i dont have a garage up at school and its getting dark..

RE: Boost issue
found this while reading up on the zine, i think this is where that loose vac line came from... unfortunately i didnt find this till like 6, and it was already dark... looks like its the first thing imma check once i wake up at the crack of noon

There is a spot where 2 vac lines connect under the intake mani, there is a little sensor under there. one line goes to the front of the mani, and one goes to the secondary air pump behind the engine. that is another spot to check,
