I know the stage 1 kit is covered by warranty, but if they screwed up the wiring by making a faulty connection it could give a false sensor reading which might make the computer think it's over boosting. It sounds like they don't know how to troubleshoot the setup. Even a cracked intercooler would give some boost(unless it's split in half). A cracked turbo or open bypass will give minimal signs of boost and seems like the real problem.
