    Did you have it tuned after the install, if not that could be your problem. Most cams require a tune after they've been installed especiall for an A4

    check all your spark plug wires, making sure all are truly on the spark plugs. You should hear them click in place. I went 3 months thinking my engine was gone, and then I found a loose wire.

    Does it do it at a certain RPM or speed or just anytime you mash the pedal?

    What RPM are we talking about? Personally I would say when you change something and then get a bad reaction it is most likely in the change, but then it could also be something like an O2 sensor those wires run pretty close to things down there.
