The 06 LLY and LBZ are the same truck, different tuning.

The earlier LLY have a hot air intake, different PCM, only 1 IAT sensor (LBZ has an IAT2), and a few other things.

and the compression is less plus I think they switched to a 32? bit processor for the computer. Only the lbz's have the six speed.
