HI, been reading a lot of threads about blow off valves and re-circ dump valves. I'm about to buy an A3 1.8TQ and love the sound of the whoosh dump valve that dumps to the atmosphere but i obviously don't want to loose power. A lot of ppl have said that the car will run rich with the ext dump valve, so whould having a better air feed resolve this by supplying more air?? Or an alternative, where abouts does the re-circ DV dump to, in the air intake? If so would replacing the air box make this dump back to the system audable? Thanks for any help, Dixon.
