OK, checked a few things today. Bypassed boost solenoid by running the actuator straight off the compressor housing , I also ran a 2nd boost guage from this line so we could see the boost levels being made from the turbo. Manifold pressure was 9.5 - 10 psi, turbo pressure was 10 - 11 psi, meaning about a 1 psi drop over all my pipework and intercooler, basically it rules out any boost leaks in those areas. There are a few possibilities I can think of, Actuator could be 9 - 10 psi not the 12-13psi one that was requested, Actuator could be f*#ked, Flapper may not be seating properly, or not enough of pretension on the actuator
