coolant temp sensor might be faulty

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.
