With the traction control off and torque braking to 2,400 rpm before launching my best times were 5.7 seconds to the shift to 3rd @ 57 mph. That was consistant. I have my notes right here for the G-tech. It was 68 degrees with low humidity and very light winds. G-Tech reported 5.9 seconds 0 - 60.

Don't worry about the chip. I'm very sure that if Rene isn't sure he can do it with no problems he wouldn't do it.
