no, incorrect....

the "lean cruise" only works on the 04 gto pcm from holden/australia....

the 05/06 gtos have a separate ECM and TCM modules from the U.S. and it's totally different and lean cruise does not exist for them...

Makes sense. I was replying to rickjamescc about the lean cruise working on 05 GTOs. It only worked on '04 GTOs.

I've got no clue what my truck gets. My TBSS only gets 16 on the highway. I started looking at the 04 GTO PCM hoping I could retrofit it into the truck easily and still pass inspection in NY. It can't be done to pass inpection using HPTuners.

I believe EFI Live will allow you to put any VIN in a PCM. That may be an option for some guys to switch to an '04 GTO setup to get proper lean cruise operation.
