It's strange that so many people on this list have had such a bad
experience with APR as they've been pretty helpful to me when I
initially had some problems (that turned out not to be a problem with
the chip itself...)...oh well..

I really didn't notice any rough spots unless my plugs were on their
way out. I tried some Denso Iridiums for about 10K, but they didn't
last as long as I hoped, so I went with some Bosch copper
tri-tips..they were really cheap (about 2.60 ea) and worked really
well! I also found that i had to clean the K&N filter quite often to
get the best results as it got dirty pretty quickly.

While your at it, you might consider replacing the front engine snub
mount too, as it does make a perceptible difference when beating on
your car and agressive gear changing...

Have fun! I'm waiting for my new A4 to wear in a little before I get
too much involved in mods...

Regards to all,
