Do not buy!!! The installation shorted out a wire from my fuse box to the starter where Bully Dog said they'd pay for the tow and a certified Chevy dealership to fix. Was told no after $311 fix bc it wasn't a fuse or ECM. I told the it was the wiring and they said too bad. Then every time I start my truck I have to update the software (takes about a minute). Called and said we are aware,but can't do anythin. Go to uninstall so I can return the device and the file is corrupt. Week wait for new SD

It may have made a little difference using the stock tunes, but marginal. I had issues turning the AFM/DOD off and have been working with customer service on it, but they don't feel the need to responde back to my emails. I eventually figured it out myself. Poor instructions and poor customer service, but product is "okay"
price vs product

I have a 2011 silverado w/ the 5.3 and didn't see any mpg change nor any real performance change.I've only had it for a month and I'm still learning stuff about it. As of right now it's not worth the money.
