I have a 2005 gmc duramax with the LLY. I have the opportunity to get a good deal on a banks six gun tuner with PDA, but its for the 2006/7 LLY/LBZ. Will the programmer work on my 2005 or is the wiring harness different for the 2006 LLY's. I know they put some more emissions stuff on the 2006 LLY.

how good of a deal are you talking

A buddy of mine is getting rid of his 2006 LLY and he said 400.00 for everything, including his speedloader.
