08 2500 quad cab 4x4, Suncoast mega rebuilt 68rfe with Suncoast flexplate and torque converter, heater grids removed and intake milled out, S&B intake, AFE 4" exhaust, EGR deleted, DPF deleted, H&S Black Maxx.
Other than intake, exhaust, programmer, and the goodies added to the trans, it's stock. I've been reading a little about modifying the CP3, but I don't think I'm short on fuel, but perhaps more could be added. EGTs didn't get over about 1380 degrees.
My buddy I was running against ran similar times, but he's got 5. 13 gears and a lack of traction in 1st and 2nd gears, and he ran out of RPMs at 94 mph, so we ran pretty similar times.
Some guy in a ~04ish looking mustang said "I don't want to wait for you" when I asked if he wanted to run... . dude was wearing his helmet so I figured he must be a 12 second car. Nope. We (my friend Tony wanted to make a pass) walked him.
