Warm Up Regulator.
The WUR along with your fuel head are the main components to the CIS.

The Andial unit is a band-aid, and in my opinion not a very good one. There are proven modifications to your Fuel Head and Warm Up Regulator that will support your level of power without auxiliary fueling. A good mechanic will know this, yours doesn't sound so good. There is no reason to run your engine rich. Excess fuel will wash the cylinders diluting the oil and shorten the life of your engine.

I don't think there is anything wrong with your wastegate, if so you would be over boosting. What you are describing sounds like turbo surging. What exactly was done to the turbo?

If your mechanic told you this is normal and you have to live with it you need to find another mechanic immediately. He is fixing to cost you a whole lot of money. I wouldn't drive this car until it is tuned properly or until you put it back the way it was. 390RWHP is very respectable for a CIS engine.
