2017 GMC 2500HD performance tuners programmers

[John Dell]

Has anyone found or used a programmer for the 2017 2500. I believe the ECM in these trucks is newly designed and does not work with current programmers. I understand the ECM is more complicated then previous models. I would like to program for larger tires and adjust my shift points up to match the larger tires. Thanks.

Say good buy to your warranty if you do so. However im pretty sure that DiabloSport has the 17' covered?

HP tuners works for 2017 2500 6.0 6 speed. I think it might be the 8 speed trans that has the hand held type tuner companies struggling.

I don't know of any custom tuners that have cracked the l5p yet. I wouldnt touch it with a handheld canned tune.
