I got AA tune last April and tested it thoroughly on street, hwy and track. I have a few other mods also and in combo with this tune the car has plenty of power while being balanced. The bad thing is that I need to install LSD now :-)
I attended Watkins Glenn and Poconos HPDEs and had other drivers stop by and ask questions since E46 M3s couldn't keep up especially on straights.
This is my fav mod beside suspension upgrade so far and hope that AA is ready to release either a supercharger or Stage 3. I am looking forward to the news before Xmass.
Andy, got that!?
