No boost, no spooling, wtf?

This happened to me the first time I boosted high. Trust me the way that sounds, its a boost leak. Its probably a coupler. If you have aftermarket intercooler piping...check that when someone is revving it up a little to see where the air is coming from. It might just be a slit in the coupler. Plus, does it shudder when you are full throttle when it doesnt go above 2 psi vacuum? If it does, thats a boost leak.


And what do you mean DSMs wont run like that without MAF translators?

Thanks man, we'll see what happens when i replace these couplers and boost leak test it again.

As in it will be sucking in air after the maf, so it won't be measured... therefore it won't run. I've blown a coupler off and once almost off, and it wouldn't run unless I held it above like 4k at a steady RPM. Kinda like not having the recirc off, but wayyyyy worse.

Dont just replace the couplers...they are expensive...and thats one thing our car isn't. lol. Just check to see if the clamps are tight...and not over tightented. Because when they are over tightened, they tend to bend and let some air out when being pressurized.

Measured or not by the MAF...when an intercooler pipe blows off...your car runs rich...really rich. Especially when there isn't steady flow of air going into the intake manifold.

Well I know for a fact that one needs to be replaced and another one need to be moved. But I don't get why it would change over night.
Not trying to be hard-headed, I'm just not really udnerstanding.

Cmon man you have had a turbo car before...shiit happens. Vibrations, pressure, etc causes things to get loose or pop out. You know depending on the angle you put the coupler in...determines how long it will stay in place. I actually had waaaay too many problems with couplers and piping popping off in the middle of the highway, etc. So now, I just put a drop of super glue between the coupler and piping...just enough to hold it in...but just enough to pull it out if needed. I have had to take off my bumper on the side of the highway one too many times...trust me you will figure it out. Just take your bumper off and start working things one at a time.
