I'll check the fluids tomarrow.
I am aware that white smoke in the exhaust is usually indicative of either coolant or water being present in the combustion chamber.

I'm also going to go over the TSP, the cranke angle sensor, the fuel pressure regulator, the mass air flow meter, the variable resistor and the BAC valve.

I am also replacing the old air bypass valve with a new blitz ss BOV. I have heard that if the bypass valve is stuck open it will cause the wrong fuel map to be selected and possibly cause the rough idle, lack of power under boost and the smoking due to either too much fuel or too mucg oil.

Thanks again. Keep the ideas, comments or questions coming.
