    Hi ppl,
    have just had my a4 chipped, and have been advised to replace my dump valve(purchased years ago WHEN i thought the noise was cool). They told me to buy a recirc valve with a second spring, to increase bottom end pull. There are a few im looking into, the amd hyperboost valve(in group buy section),
