Are you talking about free reving it in neutral? If so, it shouldnt develop much, if any, boost. When free reving, there isnt much load on the motor, exhaust flow is too low to spool up the turbo. Motor must have a load on it to produce boost.

Most of these cars wont boost much at all with no load on them... the small rise you get is what mine did when the waist gate accuator came unhooked. Check the accuator...

Ah, I'm not running a wastegate actuator. Or a wastegate, for that matter.
