You should post this in the FI forum along with details on your setup and various feedback from your instrumentation, wideband, EGT, and OBD data would all help. You're being way too vauge for any type of useful help. It also sounds like you a bit over your head. Did you install the turbo?

well it seem like i am running rich ......but when i push the car and boost starts to come it just seems like the car wants to die at the same time the wastegate is open. me and two of my friends that are turboed put it on ...i just have not felt any big boost .....and at idle my car ruff it jumps from 1000 to 1500 and keeps bounceing .....anything you can think of any thing i should look at

Check your wastegate actuator. It might not be clamping down good enough and is blowing open under the sudden boost situations. Easing into it might allow it to seal enough so that you build some boost.

What are you using for tuning? Are the plugs the right heat range/gapped properly? Like I said the more details on your setup the better.
