The biggest benefit so far is better shifts, they feel quicker and more sure now. The gas mileage is up less than 1/2 mpg for city/highway and a little more for highway driving. The Hypertech will take 4 years just to pay for itself at that rate. That said, I am eager to find out if the Hypertech helps when I put oversize tires on. On my old truck bigger tires cost 3 mpg. I hope to at least break even with bigger tires and the Hypertech on the newer truck.
Thoughts on Bully Dog GT
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!!!
