Please forgive the newbie question. I'm trying to raise the speed limiter on an '07 Tahoe 5.3 E38 with OS 12605898. Is H0129 the only one that needs to be changed or are there other things to change also? Do I need to do anything in the Trans module? Thanks.

Just switch the values in the speedometer tab. then press ECM for the limiter, not other module.
