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

I'm hoping (for your sake) that I just got the cool white ones by mistake. I never followed up with them to see what was actually going on with mine.

Installed a Diablo 87 octane custom tune and shutoff the afm (v8 all the time now) and my mpg went from 12.4 to 15.2.

Would your numbers be thrown off if you use anything other than 87?

 

[Joew311]

Little blurry but this happened on our way back home from Gatlinburg, TN (55555 miles). Drove 811 miles there and back (not counting sightseeing while we were there. Averaged 18 mpg's out and 20 mpg's on the way back.

Your fog lights are on....how did you get the temp on there? Mine is on my rear view mirror

Because his is a later model. Around '10 or so is when they started doing that, Phil.

Both my temp and compass is in the DIC, I don't have anything in my rear view mirror. My 2005 Silverado had it up in the mirror though.

Mine is a 2013, so I guess that's why.
