It sounds like you have the very common problem with an on throttle turbo surge. The compressor wheel is actually mis matched to the turbo housing in that application. There is a fairly inexpensive fix for it. There is a replacement compressor wheel for inside the turbo that corrects the problem. You can go with that or you can replace it with a new performance turbo. The wheel is going to be under $100. PM me for pricing.
