Have you checked your fuel pressure?
Are you sure it is over fueling and not perhaps running lean?

yes if your lambda is faulty that will affect fueling

I did turn off the co2 on the pfc. Still the same. So far I replaced water temp sensor afm. Lamda sensor checked all boost pipes. Thought problem was on pfc but changed to stock ecu still the same.
