i have been looking to upgrade my 06 lbz with programer or some thing i have heard alot of people talking efi live i ran the bully dog programer on my 06 lly but would like to know info if possible want the most bang for the buck i also tow a montana 35 ft fifth whell camper for time to time but not that much thanks

If you will read in the EFI section you will find the info you are looking for. It appears that EFI will be out very soon for the LBZ. I think the scan tool is out now.

If you want to learn how to tune your truck and thats the direction you wish to go then look at EFI live. If you want to plug and play with something get a tune written by someone else(box/programer/or swapped ECM). Totaly depends on the direction you wish to go......
