What did you do to your NNBS GMT900 Tahoe/Yukon Today?

I noticed thecopcar driving a bit rough yesterday. Today I noticed the light on the range afm device was out. Flipped the DIC to instantaneous mode and noticed it was going in and out of V4. I have the spare range unit that had been in thethirdtwin. Will try it tomorrow.

Does it have a warranty? Just curious. This is the reason I'm scared away from the nnbs.

just use a canned tune or get a tune, then no worries about any "plugged in" things failing.
when I bought the denali I had already bought a handheld tuner and as I drove it off the lot I parked down the street and turned off all the nannies and drove it 7 hours home, hauling ballz across the desert lol

Could also be the fuse for the power to the OBD2 port.
