1) Let it warm up. Is it cold where you live?
2) It's a big turbo, not going to spool at 1000rpms
3) That whoosing noise is probably your ebpv(exhaust back pressure valve) that closes when the engine isn't up to temp to force back pressure to help it warm up quicker. If letting off the throttle or applying more throttle gets the nosie to stop, that is your best best.
