I went through EVERY single vacuum line tonight....vac tested the canisters and each line... EVERY THING held vacuum fine. I wonder if I got my second set of rebuilt rbs with a faulty wastegate actuator? I am so lost as to why I can't build any boost.....I posted a log on n54..

My PWM or wastegate duty cycle as they said is maxed out so for some reason my wastegates aren't closing. .. I check every connection tonight

Since you have ruled out vacuum and solenoids as a possible problem...

If you haven't done so already: pressurize the intake system to 20 psi and check for leaks, also check to make sure you fitted the downpipe to turbo clamp correctly, eg: not touching the actuator rod.

If those check out then you need to check for back pressure issues like clogged secondary cats.

Try and manually move you front waste gate actuator arm...

Another good experience with Luke. His new shop is great as well.
