so i have had my car turbo for about two months now with a hahn stage 2 kit w/ sidemount intercooler. everythings been fine until yesterday when my car will not boost! it just sits on zero and will barely creep up to 1 psi. what should i check to fix this? thanks

i would do a leak down test. make sure one of the couplers on the ic piping didnt come off or loose up. other than that im sure others will be able to give more advice. hope that helps.

i highly doubt that a cut in his boost line would make the car have no boost, mabey the gauge, but that is it.
Sounds like you have
A: Intercooler pipe blown off
B: Wastegate arm has fallen off the flapper.

Check both those things, if neither one of them is bad, you may have more problems than you think.

The new:

thats the whole point...maybe there is boost but the gauge is simply not reading any. Are you saying that you don't have any boost at all or the gauge isn't reading any boost?

the problem has been fixed...it was just the wastegate actuator. all is good now. thanks

how did you figure that out? Because my friend is starting to have some boost trouble similar to yours.
