More boost? Of course and this 3 port boost control solenoid will help you do it. 

3 port boost control solenoids are the go-to for the majority of boost control applications, they allow for precise control of boost and boost levels can be raised to around 2-3 times the spring pressure of the wastegate.

For higher boost applications consider the 4-Port boost control solenoid. 

Features:

• Compatible with all Link ECU's
• Can be used with single or multiple wastegates (Using T junction)
• Compatible with internal or external wastegates
