Do you here an almost whistling noise when you try to get into boost? If so you might just have a rather large vacuum leak. If you aren't making any boost then you likely fried your turbo.
The best way to diagnosis this would be to get some logs of the car and see if it's making boost (a boost gauge could do this too). You should also look into doing a vacuum leak test. Do a visual inspection of the engine and see if any hoses popped off or if there are any obvious leaks that you could repair.
