For sale is my Custom Tuned M-Box for a 2001.5 S4 6 speed, way better than any other off the shelf ECU. Stage 2, made for down pipes/piggies and exhaust. Should be at 330 hp or so. Very nice strong tune. Comes with rear o2s turned off, launch control set up at 4450 rpms and left foot braking enabled (you will be able to brake boost).
