So the only change was the clutch? It was tuned and ran fine before? Did you have to disconnect the exhaust or remove the headers?
If this is the case I would look for an exhaust leak near the motor. If you have unmetered air entering the system upstream of the 02's, it will think that it is running lean and attempt to correct by adding fuel.
