PWG N55 vs N54 boost control setup

This may be a dumb question but I can't find the answer anywhere. I just came from the N54 world which of course uses vacuum canisters etc for wastegate control. How does this different from the pneumatic/vacuum wastegate N55, or does it? I haven't seen a canister on the N55, and the N54 doesn't have control issues that some have with the PWG N55, so something has to be different. Anyone know? Thanks.
