They are Lexion Type203.

 

I haven't taken neither car to the drag strip yet, so I don't know. But from my butt dyno, I can tell that the A4 is much quicker at the low end then starts to fade at the top end. The TSX is definitely slower at the low end but it feels much quicker in the top end (probably because I have the reflash done). If I get the APR flash for the A4, it will definitely be quicker than the TSX.

 

Whatever.... [sm=smiley29.gif]
