Thoughts on Bully Dog GT

Reviewed By Daniel F (Valley, AL) Reviewed for a 2008 Chevy Silverado —4/22/2017 1:11 PM

Very easy to install, I even hard wired it into the fuse block under the hood so it works on/off with the ignition. Over all it's a great piece of machinery. I was able to turn off AFM, which is great. Also programmed it to performance tune on engine and trans, and within 2 tanks of fuel I am seeing a 3 mpg increase, that's awesome because I was only getting 12.6 before the programmer. AutoAnything even lowered the price for me, so don't hesitate to chat with someone and ask!!!

Power up - Gas down

Noticeable increase in HP and firmer shifting at higher RPMs. Lost MPG in city & HWY which was disappointing. '14 Silverado w 6.2L
