Believe me, any help off the line would be GREAT!!
Owning a 3/4 ton truck, that is actually a very good time. I bet your stock truck would beat mine in the quarter mile even with all my mods. On the other hand, it might be close if I were still running 245's and not 285's. How is the truck off the line with the new 6 speed? Mine is in desperate need of a cam with some low end grunt to combat the 2.48 1st gear. Doesn't the 6L90 have like a 4.03 1st gear or something like that? I want one.
The 4.03 gears feel nice off the line at part throttle, 1st gear doesn't last very long though. At WOT the computer is so restrictive off the line that the steep 1st gear doesn't do much. Whatever it is with the computer it doesn't let loose until 4000rpm and then again around 5000rpm. It literally feels like two small nitrous shots at those rpms. 
My EFILive cable is messed up do to a BETA update I decided to try or I would've had it gone on Saturday. Hopefully they come out with a new update soon.
Thanks mang.
