Default pressure tested my car today. there seems to be a leak behind the motor in the center.
i just changed the the vacum line from the manifold. what else could it be. other then behind the motor, there were no other leaks i could hear.

it doesnt seem to be coming from to low( near turbos ) i hope this is something i can fix.

Thanks

I had a plastic tee break back there. Heat made it very brittle.

1) Go to Sears, 2) Buy Automotive Stethoscope, 3) Find exact location of leak, 4) Fix.

Sounds like the dreaded waste gate line. Impossible to get to. GOOD LUCK

Default doesnt sound that low. theres a braided line coming from under manifold
that looks like it in bad shape. i am hoping its not to bad. if nothing works ill have to take it in somewhere.

Default I think my head has been in 2.7T engine bays more than my 1.8T engine bay.
... and I've definitely pressure tested and repaired leaks on 10 2.7Ts for every 1.8T.

Nah, that would cause overboost, not underboost.
