Can you turn this up, as im only running 6 psi, boost controller 3 1/4 out, and boost gauge saying 6psi. No air leaks, ive sorted that, and i had this problem before i had the dump vavle on. No air leaks from what i can see!!

My question is, can you turn this up, to get more psi?

 

What exactly are you asking here mate, can you use the actuator to adjust the boost, yes. What is the boost controller bit all about?

 

oh, i still have a problem then...... its turned up.
