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.
