Speedometer Correction with GM GDS2?

[madmax032]

Good Afternoon!
I would like to switch up my tire size (diameter) on my 16 Tahoe and correct my speedo but after going through every single module on GDS2, I couldn't find an attribute to change. I found load range and tire pressure but that's it. Is there any way to do this with GDS2 or does a standalone programmer or HP Tuners?
Thanks!

the only way it's going to change the speedo is if there is a option to change the wheel size.
Generally speaking otherwise gds2 is not going to change much of anything as a standalone product it is for testing and diagnostics, when the testing is done everything goes back to normal. just like the tech2 on previous generations any changes allowed are very limited.

I believe that a programming change is required for what you want to do.
