If you have two boost control solenoids jet should be 0.9 or 1.0mm bore and 7mm long. With single solenoid 1.2 mm.
With two solenoids you have to check if pins 41 and 63 are linked together. Try to run ign3 output test (DO NOT FORGET TO DISCONNECT IGNITION COILS FIRST!) and try to find out which solenoid is making sound. If both boost control solenoids are disconnected there must be no sound around engine during ign3 output test. Sometimes........
Are you running v3.4x firmware or previous version?
MAP or MAF controlled?
