Buly,

I can only echo what Rusty said about "danger, danger." You've got runaway boost, irrespective of the fact that you removed the wastegate. The wastegate size is not sufficient to get rid of all the boost you're producing. That boost past 30" MP makes the turbo go even faster, which feeds back even more to the insufficient wastegate--it's a recursive cycle that takes you to that very high boost level very quickly. All the racer boys working with the stock turbo complain about it. 

All that boost requires tons of fuel. Think .65 BSFC, guess what horsepower you're producing at that boost level and figure out how much fuel you need to deliver. Then re-check all your bottlenecks: fuel injector sizes, fuel pressure, pump sizes, fuel computer programming, everything, 

You need to be able to control that boost, friend. It could go uncontrollably lean on you and....

The symptoms all tell the same story.
