the 2011+ ones have run 12.2s on DSG and new software. They will otherwise run 12.4-12.8s depending on OEM software. My best friend is running 12.9s in his with a 2.2 60 foot times at 110. He can not launch it for ****. They are a great match for a 2011+ 5.0 stock for stock. Edge to the GT under 100. Although the 5.0 has practically erased the "no top end" rep of a Mustang.
