What kind of wastegate?

What kind of engine management?

Noga, you may have a vaccum leak, that usually cause inconsistancy with boost level.

Double check your boost controller vacuum hoses to check if you hooked it up backwards.

double check the vacuum source to your wastegate is operating as it should.
