Long term owners of BlackBear Autocal tunes.
Probably looking at 5 years on my BB tune. Bought the tune with the supercharger bundle. Love them both, installed the tune first and it made the truck feel like 500 pounds lighter. With the SC, it is awesome. I have reached back to BB several times over the years for tweaks and what not...- brainfried

What’s your MPG
I have a 2012 Yukon Denali with factory tires and about 55K mileage. It has a 1.9L Magnuson supercharger with a 10psi pully, BlackBear tune, headers with cats and a Borla sport exhaust.

Get a catch can before any mods.

New Yukon in Houston Area
Welcome me, I am glad to be here and find these vehicle specific forums extremely valuable and I never leave a vehicle stock. I have a 2012 Yukon Denali that I got specifically because of the 6.2L engine. I previously had a 2011 CTS-V with the supercharged 6.2L LSA. It was my first car...- brainfried
