I recently rebuilt my motor and installed megasquirt. I finally got megasquirt running very well and am ready to run more boost.
I have a tial 38mm external wastegate. I had the 8psi spring in... I changed it to the 1 bar (14 psi) spring. The boost remains the same.
I was under the assumption that a 1 bar (14 psi) spring would allow 14psi of boost and if I wanted MORE I needed a controller... Is that not true? The gate is opening around 5-6 PSI and I can barely get it to creep to 8 PSI...
Right now I have a single vacuum line running from the manifold to the side port of the waste gate.
