Has TAP come out with the A4 2.8 chip yet? Last I checked it was due in October, costing $499. I am very curious to hear results people have had with the chip. Along these lines, I'm also curious to hear how people have upgraded their A4s and the difference the upgrades made (sway bars, headers, exhaust, tires, etc.). -Tom '97 A4Q being shipped to US now.
