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.

Sorry, I don't have an answer for you, but i was curious if that guy still has your old Tahoe? That was one cool ride. Hopefully it's still around and in good shape.
@Tonyrodz

Cool ride indeed. Last I saw is yes. It looks the same. He deleted the Esky rack and added the front chin spoiler back on.

He had a few dings pulled and the paint corrected. It pops. Still rolling the TBSS 24s.
