Turbo's are not spooling when stationary - so hence no noise.

Was the old Turbo cactus - hence replacing.. Perhaps this one is spooling correctly with the specified PSI of boost...

You could also check to ensure all fittings from the airbox to the throttle body are secured and tight - and that SUPER LOUD noise is not actually boost leaking out of piping..
 
was the noise there with old turbo? or just new?

who did the install?...were all gaskets replaced with new ones?

sucking noise? squealing noise? grinding noise? high pitched? low pitched?
