Unplugging S3 Exhaust valves

I know this is an old thread.....
I have vcds and have put car in dynamic, its got louder, then ive switch the car off, put in 'P' then in vcds byte 9 unticked bit 2 (exhaust valves installed)
Car was warm, but it was cold outside, i had condensation/smoke coming from all 4 exhaust tips, inner tips were warm, outer tips cold, (blowing cold air)...... Maybe warm up after a bit om not sure..... have i done it right?
