I put a Cat Test pipe on the 06 A4 Quattro and put it back on the dyno after I tuned it again. I held the torque back a little down low and it seemed to help it run much stronger up top and it really takes off at 4k and pulls hard up top on the road, will probably lean it out just a little bit past 6k. Put down 235whp and 270wtrq, that would be 290bhp and 335 ft-lbs with AWD 20% drive train loss. It feels very strong and it handles so much better than the Saabs I usually tune :-) Its a rocket ship now. Next step will be front mount and probably right to the disco potato :-)JZWhttp://www.facebook.com/photo.php?fb...type=1&theater[IMG]
