Question:
I have forgot to mention that the trucks have the Diesel Duramax 6.6L L5P engine. I’ve noticed that some reviewers mention that the speed limiter cannot be adjusted for these models using the suggested SU#5845 part number. I’d very much appreciate if you could confirm again before I place the order.

We have SuperChip Flashpaq programmers that fit your 2017 and 2018 GMC Sierra 2500 with the part # SU5845 for if you have a diesel engine or the # SU2847 for if you have a gasoline engine. These can make the adjustments you are wanting but you should note that you can only install a programmer on one vehicle at a time. So you'd need two programmers if you need the adjustments to be on both vehicles at the same time.
