Trouble with LS swap, need to bounce some ideas around

Plenty of information on this topic available on the internet - if you look in the right places.

The Gen 3 DBW LS Trucks that used 1Mb PCMs, also used TAC Modules and electronic Accelerator Pedals (APP), which may be divided into two categories - the early versions from 2003 to 2005 (which are mutually interchangeable), and the later versions from 2006 to 2007 (which are mutually interchangeable).

If you program a 2006 or 2007 DBW 1Mb PCM with a 2004 DBW calibration, then must also switch to the earlier (2003 to 2005) TAC Module and APP.

These parts are typically inexpensive at your local wrecking yard (and readily available). Make certain to also get the short wiring harness that connects the APP to the TAC Module while you are there.

Thank you for the reply that's kind of what I was worried about, I may try and look around for a 06-07 bin file and rewrite my computer on Monday if I can get everything together. Again thank you so much, im hoping its something as simple as this. Im also planning on reopening up the harness and double checking one particular ground.

Thank again LRT, I pickup up a TAC module and pedal from the wreckers yesterday drove down and installed them. Problem is solved!
