It's because your timing takes a nosedive right when the car launches.
timing is that of a FI car. even lower.

raise stall torque management
work on your timing and AFR for more low end power.
i agree with ROG2R. get rid of torque management, tune the fuel delivery, and make sure there's no spark knock. i have the same truck and it gets up outta the hole now.
One thing that helped mine was removing the negative timing in low RPM-high flow rates. I have not opened an 08 to see if they still have negatives or not. Just keep an eye out for knock.
