2016 GMC Savana LGH Duramax with 9B9 70mph speed limit
Looking to remove the 70mph electronic speed governor on this vehicle.
Tried doing it through ACDelco helpdesk line and get the VCI#, but they refused to help due to vehicle having a salvage history.
VIN 1GTZ7HFL 00000 2292 (antiSEO measure, replace 00000 with XG126)
Boot Software 12664192
Main Operating System 12660050
Engine 12660054
This is a pretty rare vehicle, and the closest one I was able to find was a 2014, but I don't think it's a good idea to use that file.
Advice, or base tune?
