Nope, went to school in Madison. Originally from Chicago (I know, I know) but now I'm out in Sun Valley, ID

Well, I don't know if you have experience with the Pulsar LT. If not, it is a fantastic chip. It does a lot for your truck. I highly recommend it! Ride159 got a hell of a deal! I paid 550 for it. Solved all my issues. (With the truck anyway)

From what I know, the refresh 22.5 and up it does not work yet. The gm global B ecm hasn't been cracked yet by the makers of the pulsar. I've been waiting lol.

I found this module, claims to work on all Yukons, EVEN locked ECUs:

1996-2025 GMC Yukon – Stage 3 Performance Race Tuner Chip Power Tuning Programmer T2 – ProtuningUSA

They are in Fort Smith, AR and seem to have found a method to deliver gains on stock units that other chips can't.
