Thanks for your reply but they are all DBW bins, I think an 04 express van is DBC if anyone has one?

It doesn't matter, 125 87 603 OS is capable of both.

It's the hardware that makes the difference.

I have been told that it works and also doesn't work so wanted to cover my bases by starting with a DBC OS

I have asked the person that sent it to me if I can share it on here, if they say yes then I will gladly share it.

Hath,

Look at it like this, If the OS changed one BIT, GM would have changed the OsID. Seriously, they change the ID for seriously stupid simple reasons.

That means the change would have to be in the Calibration ... Thus all a tuner has to do is make the appropriate adjustments and presto you get what you want.

Have a look at the file you posted with joukoy's tools.

-Enjoy
