    Speaking of dump valves, mine gives off a little dump valve noise as standard, is this normal? ha

    Can the 2.0 TFSI run a dump valve without throwing a code and running poorly? The stock valve is a diverter valve so it puts the dumped air back into the boost circuit instead of dumping it to atmosphere. Normally dump valves just cause poor performance on these engines.

    you dont need a dumpvalve if you have a remap and an induction kit, the noise is loud enough already! :p

    Yeah alot of guys up here run the 2.0TFSi with a dump valve. Recirc valve out and dump valve in.....personally I wouldn't as if you wanna run the new GFB DV+ valve you have to have the orginal electronic top half that the DV+ slots into. Far better in my eyes.

    Ok cheers for the advice. It makes a noise already when I let off the throttle. Just wanted something a bit louder. I am new to audi so am still learning all the different engines and mods ect.

    Personally the best bet is to run the latest forge version in recirc mode. You still get the blow off noise and it still recircs. So win win.

    Been running it for quite a while now and it's A1.

    Yes,you can.

    The S3 has both a MAF sensor,measuring air mass,and a MAP sensor,measuring manifold air pressure.

    If the MAF is either not functioning,or giving incorrect figures(as it will if you remove the diverter valve) then it will default to the MAP sensor.
    Not ideal,for the sake of some noise.
