Hey all - I don’t remember where I saw it, but last year somewhere in the interwebs I saw someone had their Hybrid Yukon/Tahoe modules flashed up to the latest GM software versions and it made a noticeable difference in performance.

Not looking to seek out that person directly, but am curious if anyone else has done the same here and what they saw for results. Wondering if it’s worth the $150 or so to have a tech plug in at the dealer…

 

doubt it and no I would not do it no way no how unless it was a necessity to fix a problem. You could actually create a problem where there was not one before!

 

was it the software talked about in this tsb? I don't know what it does, but seems like it might have reset what the 60% state of charge is and that needs reset afterwards?
