will an 05 pcm from the same exact truck work with an 06 truck? me and my dad have the same exact trucks except his has 3.23 gears and I have 3.73s. I wanted to swap his pcm to check if the stock tuning in his is diffrent than mine because my pops truck feels alot more responsive and will actually chirp the tires (mine will not even chirp them :pow: )whats the deal, do the 06s have more torque management than the 06s or what?

it will work but the speedo will be off from the different gear ratios in the rear.

Just save up for a tune... you'll be way faster than pops and you won't have to deal with a f'd up speedo.
