Tune?

[BigRed41]

I have a 09 GMC with a 6" lift. I would like to hear if anyone who has done a blackbear tune and did it help with their performance and mpgs. Any thoughts?

Yes, you'll see a performance difference and if your tires aren't adjusted for the trucks pcm/ecm it will throw off your speedo and shift points and make your mileage seem worse.

Welcome to the site. Not sure if you were trying to post from your hard drive but if you were, you can't. You need to host photos on a site like photobucket and post/link the url here.
