has a RB20DET have a standard boost solenoid? If so where is it located? Iv a aftermarket blitz dsbc boost controller,set it up & programged the boost settings as per the manual says. Iv it set to .85 bar. The car isnt boosting anymore than .7 bar tho. So only thing i can think of is there is a standard boost bontroller in the engine that is restricting it or else i need a adjustable actuator? Different views have been on this, some say i need a adjustable actuator and others say the standard one should be good for .85.
sounds like an actuator probelm to me, though worth checking for boost leaks first, cheaper than a new actuator
