This was my first time driving the 6.4 at the track and we we're testing a new tune for the transmission so I wasn't sure what to expect. I think I might can get the 60 into 1.9x range, but with only three runs I was able to get it to a 2.0

Thats impressive...every 6.4 I have driven has been a TURD, so the programmer must really wake it up. I'm sure once the custom tuning is out for it it will wake up even more.

Damn thats a good time for tune only!

so whats the story on this truck ? im interested

Glad to see they are comming around. Congrat's!
