Thats a low boost circuit A code. Hows the turbo comp wheel look? Hows endplay and up/down play in the shaft? It could also be your map sensor. I am not too keen on this one, I did have this code come up, but I was loosing oil pressure. I fixed thaty, and rebuilt my turbo, and no more code. Some one else will be along and help you better.

i figured out that the plug for the map senser came off alittle and now the check engine light went out. makes me feel kinda dumb but i guess it didnt click on all the way
