It depends. A generic flash will take less than an hour, a proper custom map on the dyno and/or road can take a full day or more depending on what you're mapping.

blow off valve willl not give you more power but will make the car run worse.
your engine runs a closed look diverter valve. this puts the charged air back infront of the turbo, however behind the MAF - mass air flow
the ECU already has accounted for this extra air and as such puts more fuel in.

if you fit an atmospheric one then expect poor running and possibly a warning light on the dash.

you need to fit a diverter valve as well, bad news is if your looking for the tshhhh noise, but again this wont give you any power increase but may make the car feel more powerful is the original bosch ones diaphragm has spilt - quite common, mines didnt even last 30k.
