My tuner thoughts!
So I installed this on the basic performance tune running regular gas. I just wanted to see if basic tune gave me anything. The Bully Dog tech I spoke with said they got 17HP increase as results in there garage testing. The basic tune is definitely noticeable. I lost some power with larger heavier tires and the basic tune gave me back the power I lost plus a little. It's no race car but it's there. My main goal is to add towing power when I pull my camper, and so far I'm happy!
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.
