okay, those were exactly the answers i was looking for. thanks!
i haven't lived with either on a daily basis (yet), so i was curious to find out if there was some debilitating flaw in the K20Z3. seems to me like with a reflash that eliminates the rev hang and an exhaust, the Z3 should perform just about as well as the A. anyway, thanks for clearing that up for me.
