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

After 55 years of wanting and waiting for a forced injection vehicle, I finally bit the bullet and installed a Whipple 2.3L supercharger on my 2007 Yukon XL Denali. I'm looking forward to some fun times in the near future.

well I requested some changes this past summer and they sent me 2-3 different tunes and I mistakenly thought I had put the original back on it but after digging around I found it was really from july/24, how I screwed that up I don't know and how I didn't find the 2021 one on my computer until several tries I also don't know I searched 4 hard drives because I normally backup everything and still only have 1 copy so going to back it up now......

At least you got it sorted!
I actually need to find my backup though the OEM tune now that I think about it

Been busy with work and end of year. I picked up this 2008 LTZ two weeks ago with 115k miles. It's all stock with the exception of a Kenwood HU and new speakers all around.

Keeping her stock. Will be replacing the work out shocks with new OEM pieces soon.it has the Z55 suspension on it.
