[QUOTE="UnleashedBeast, post: 14814485, member: 112023"] Thank you Shaun. Absorbing what you posted, that means venting the bottom (side) port of the wastegate to atmosphere, which would require a much lighter spring to achieve desirable "low boost" scenario. Then, you use the top port of the waste gate for the boost controller solenoid to "add" additional pressure to the top of the diaphragm, effectively making it require more exhaust pressure to open the gate. This increases boost with a fail safe in case you lose a vacuum line. The gate will default to the light spring pressure only. Question, is there a maximum increase percentage over spring tension only that boost can be increased? For instance, gate pressure (low boost) is set for 10 PSI. Is 100% increase feasible (increased to 20 PSI using the controller)? [/QUOTE]
