20 bucks says your intake piping from the filter to the turbo is blocking off due the amount of vacume. See if you intake hosing is soft and has signs of kinking or remove you air filter and try again.(Removeing the air filter will reduce intake restriction, just clean your air box out before you try it so you don't dust the engine). Same thing happens on some of our older mining gear that dont have intake restriction gauges fitted, usually because the air filters are chockes.
