06 LBZ PCM and TCM question

[SSTuner]

First post to this forum.

Wanted to know when correcting the speedometer for larger/smaller tire, do you modify parameters in the PCM or TCM?

Thanks in advance

I currently am beta testing the Edge Attitude, not happy at all. Can't change the speedometer. I want to buy EFILive as soon as it's released.

I use LT1Edit(OBD1) and TunerCat (OBD1) on my 96 OBD2 to OBD1 converted supercharged/6-speed Impala SS.
