the difference is definitely noticeable. although i have not yet gotten to work with mike for a proper tune, the pull comes in a very predictable fashion--it feels like what the a3 should've felt like ...a bit more peppy lol
can anyone else chime in? i dont know how to describe it, because this is the first time ive actually driven a peppy na fwd car (i dont want to say high, because the vicinity of 200 doesn't seem all too high anymore with today's newer engines)
