Folks, Does anyone know (at a high level) how the APC controls boost pressure on a '97 Aero. Is it just through the wastegate or something else? Does it hold the wastgate closed to gain pressue or open it to releive prssure? I noticed that there are what appear to be three vacuum lines running off the APC control valve to the turbo area. Thanks, -- E.R. Sterbenz ericnopsamth.com
