Whats the spec of the engine ?? Still runnin MFi ?? Standard intercooler ?? Out the box they run about 7-8 psi, how new is the actuator ?? You can adjust the pre-load on the actuator but to be honest I wouldn't run much more than standard until set up to check AFR, timing etc. If you can set the timing to 12 degree BTDC when idling around 1k rpm -/+ 200 rpm & .7mm plug gap. Then try get the CO set 3.5%.
