I used the 87 Octane tune, shut off AFM, and set the tranny to Firm setting. Everything worked as set. I found that the shifting from first to second was a little harsh so I emailed Mike at Diablotiune and he set me up with a custom tune for the tranyy. Great customer service!

I installed the Bully Dog tuner in my 2009 Silverado and the results were amazing, the power and gas mileage improvement was outstanding. This thing really woke my truck up, it's even more easier to turn over my 35's.
