So my first run last night was a 13.1 but I kinda got Launch control figured out an the second time ran a 12.8. My mods include K&N drop in filters with deck plate mod to the factory air box, stage 1 reflash from Tork Motorsports, Inlet/outlet of the primary cats ported to 1.75in, primary/secondary cars gutted, HKSm40 plugs, Tork catch cans!
