GT Tuner

Product works as described. However the install instructions are very confusing. The instructions that came with the device said to use the USB stick to down load the GT load data but the down load program would not find the USB device. I had to use the GT device to down load directly into it. The layout of the on line instructions are confusing because they mix Gm, Dodge, Ford and others together in the instruction layout.

Drastically improved

This tuner drastically improved my trucks driveability and gas mileage. I went from getting 15 at 75 mph to 19.8 at 75mph

Save MPG!

I mainly got this to improve throttle response, adjust speedo, and hopefully save MPG. It has definitely increased my MPG the rest it didn't help with, although I can tell it added some tourque. I will update this once I have put some custome tunes on addressing my other issues. But I'm happy with my purchase just with the almost 8 MPG i gained! I drive a lifted Silverado so I will always be searching for ways to save on fuel

Once installed it made a HUGE difference on the performance of my 2015 Chevy Silverado Highcountry. Amazing results, now I can burn rubber!

Installation requires a software download. The unit is not Mac compatible. It requires a workaround remote session with a bully dog tech controlling your personal computer. Also, final setup is not self explanatory and the instructions are vague. It takes trial and error to figure out. I do get 5% better gas mileage 5.4L V8

Love it

Great product. Easy to install. I'm running 35s and can already notice a significant change in shift points and power. Can't wait to start downloading custom tunes to unleash the beast!

Wanted better response. Got it! Nice change. I have an automatic transmission. But like fast throttle response.
