they took the tsd extra cab from 12.40's to 11.90's in one fail swoop ! that included the early lockup that Bentley figured out with chris at tsd . huge difference. the 6.7 has made solid repeatable power but was never showing it at the track until this new trans stuff. my truck is MUCH faster with the early lockup.
I knew the tsd truck benefited greatly from it. I was just curious about his since it's heavier and probably not making as much power. I know when I try and launch in second gear it's a real turd off of the line. It definitely takes some good power to make it worthwhile.
