Hi guys,
I have a 1988 widebody EU specs, so with the 4g63 8 valve in it. I have a Turbonetics stage 2 turbo upgrade. This is a 16g with internal wastegate. The wastegate actuator is a triple port actuator. When I hook it up as it should be the boost is set to 15 psi, but for my set up right now this is too much. So I want to lower the boost. Is it possible to hook up a second pressure line to the second port, which is now fitted with a vacuum cap. I have left the third port open as written down here somewhere. So I thought that when I hook up an extra pressure line to the second port the wastegate will be opening at 7.5 psi or is this BS thinking of me?
