It should reduce it. Than I go to stage2 – all out :)
No, it won't. I think the turbo will tend toward overspeed more with the wastegate gone. Nothing to slow it down.   
Back to turbo 101 for you John :-) 
 
OK. You're right. Open wastegate = less exhaust pressure through the turbine = less rpm.
However, this wont save him. I think there's still enough exhaust pressure to overspin the turbine at altitude. If I remember right, my wastegate was wide open when "she blew". :(
 
Rusty (I bet Dave will make you a good deal on a -B drive)  
Not as good a deal as I can make you on a slightly used stock turbo
