Yeah, 2012LS3VERT beat me to it. Even with my [sh*tty] current tune in the low-600s, I easily & accidentally broke my 325/40/18 M&H Racemasters loose from a stop, and that's running a 3.73 ZL1 diff. Even back when I was making 60 rwhp less, you can imagine how crazy it was running 4.10s with street tires, before they finally broke!
