vacuum leak by driver side A pillar

[Rafa98gst]

This Is Driving Me Insane , An Obvious Vacuum leak Immediately Under The Left Front Tweeter, NEar The A Pillar.... The Sound Changes Under Various Loads, Levels Out To No Sound When The Pressure Inside The Manifold Levels With Atmosphere, Also Changes Violently Under Heavy Loads, Significantly Changing From "Vacuum" To An Obvious Pressure Sound Once The Turbo Spools Up, The Leak Has GotteN Louder, Not Only Annoyed BY The Sound, But The Car Has NotBeen As Responsive As before....

Do you have an aftermarkey boost gauge hooked up in the A-piller like most? That or the break booster might leak. Do a BLT and have a friend in the car to pin point the location.

No Aftermarket Gauge, I JustGot The Car, Mostly StocK...I'm Taking All The Plastic Panels Off, To Take The Top Part Of The Dash Off So I Can Pin Point The Leak ... Literally On The Seam For The ToP Dash Piece And The A pillar

Do a boost leak test then. That will be eadier than taking everything apart.

Previous owner probably took the boost guage out and didn't take the line for the guage out.

+1 this is what I though too!
See if there any vacuum line running from the intake mani area and throw the firewall.
