Best 0-60 time

Hey guys, I've only messed with the m lap timer a few times and my best 0-60 time is 4.4 seconds in a 6mt. 4.4 seconds was with launching the car at 3500 rpms in sport plus mode and I have never tried it with dtc off. I am fbo with a gthaus resonator back gtc exhaust and a stage 2 jb4 with 4 gallons of e85. Would I be getting better results with dtc off??

Thanks in advance for the suggestions,

Greg.
