I'll just stick with my 89 for now.
What did you do to your NNBS GMT900 Tahoe/Yukon Today?

Take these info sites with a grain of salt. Unless it's nearby, always call the station first to verify that they offer E85, and that they have E85 in the tank. I've been disappointed before....

Good call on a 5.3. It cost more to run E85.
Good advice. I will do that since the station is fairly close. So you're seeing a fairly significant power/performance increase?

Yes, plugs into OBD port. It also has a USB-C port on the side along with a microSD slot and two buttons. Not sure what the microSD slot is for, maybe some kind of programming.
When you first get it you either plug it into the OBD port or with a phone charger and the included usb-c cable to power it and using your phone to connect to it's wifi and get it configured to connect to your home wifi so it can update. It will also auto update when parked in the garage or driveway and connects to your home wifi.
I bought their OBD splitter cable, which has one end setup to replace the OE port, then this can lay up under the dash out of the way and the OE OBD port looks normal and can be used with like my OBDLink bluetooth dongle.
To get to the menu to setup some functions, like fold mirror at every shutdown/startup or to switch on the backup camera for a few seconds ever time you put the turn signal on, you have to turn on the cruise control button then use the manual shift buttons to navigate the menu through the DIC.
For other things it uses the sideview mirror adjustment control (up/down/left/right) buttons to activate features, but only when the left/right mirror selector is in the center position. like if I want the backup camera view on the nav screen while driving I can press the down mirror adjustment button.
It does a cool slow gauge sweep when starting the vehicle, and also displays "BT DieselWorks and the firmware version in the DIC. I'll get a video of that in a bit.
Oh, to disable the TPMS system, the device has to stay connected, but if you want to change the pressure the low tire warning comes on at, it doesn't need to stay connected after setting it up.
Will also allow programming up to 8 key fobs. I know starting in 2010 I think, this option was removed from the DIC.
will show engine oil pressure, coolant temp, trans gear, and torque converter lockup status in the DIC when the right arrow on the mirror D-pad is pressed
You can have it High Idle at 1200rpm so it warms up/cooles off faster
There's also a "SecureIdle" feature, which locks the gear selector in park while the vehicle is running and you take the fob with you and lock the door. Like if running inside real quick and want to leave vehicle running. If someone gets in they won't be able to get it out of park.
Good thing I don’t want E85. There’s only one station in Oregon with it, and it’s a 25 minute drive each way for me.

I can notice it. Runs stronger and the shifts are smoother.

NJ doesn't even sell E85.

Here's a video of the gauge sweep after startup and a couple of pics of info shown on the DIC

Yeah, after playing with it more. I installed the OBD splitter cable and tucked this up above the upfitter box above the parking brake.
It is pretty cool being able to roll up/down the windows remotely from the key fob, and also fold/unfold the mirrors. It also seems that the windows operate at a faster speed
OH, and don't know if I mentioned that it will allow you to set the TPMS warning pressure and evenbdisable the TPMS system all together

My wife is laughing at me, asking me when I would actually use many of those features like remote window roll up/down

That's not the point! Does she use all her features? Okay, then.
(Not marital advice)
He probably would really like her to use all her features.
