Using enthusiast based "freeware" means that you need to self-educate - especially to be able to make various combinations work correctly. If you have no idea what you are doing, then you should not be using freeware - it would be safer to purchase commercial tuning software.

There are many threads on the differences in the GM Gen 3 Truck DBW systems. The short answer is that 2003 to 2005 models used one system of parts, while the 2006 and 2007 (classic) used a different system of parts.

If you wish to program a 2006 or 2007 PCM (1MB P59) with a 2004 calibration, and it is DBW, then you will also need to change the TAC Module, APP (pedal), and the short wiring harness that connects them.

Here is a thread from the EFILive Forum:

https://forum.efilive.com/showthread...-my-2006-truck

EFILive does not offer Custom Operating Systems (COS) for P59 PCM Operating Systems (OS) after the 2005 model year. This means flashing the PCM with an earlier COS, and changing the hard parts of the DBW system to match.

thanks for sharing your knowledge

I have a 2006 and just want to do a stock tune with the basic deletes, is the best path forward to just have someone who knows do it with HP tuners?

Or should I muck around with trying to figure it out, seems like the xdfs can be generated now with universal patcher.... I guess worst case I brick the PCM and go holley.

I have an 06 or 07 6.0L that is doing the same thing right now. If I touch anything torque management related it goes haywire.

Attached is an XDF for a 12587811 OS for 2006 P59.
