The instructions don't tell you to, but when I called Bullydog with a pre-installation question, they told me that I need a battery charger or jumper cables hooked to another running vehicle to install because of the high risk of battery voltage fluctuation. It took an hour to install and I haven't seen any improvement to my truck; no noticed horsepower increase (haven't dyno tested it) and no fuel mpg increase.

IT WORKS!!!

Very easy to use. Just follow the directions. Received the BullyDog BDX one evening and had my truck programmed the same evening. There are several settings. I only chose a couple to begin with, but noticed the extra power immediately. Ibis will it set in economy right now, but I haven't noticed a tremendous increase in mpg yet. I mainly got it for towing my camper which is 37' bumper pull and weighs 8800 pounds in the dry. So far, I am very pleased with the BDX.

Made a noticeable difference performance wise on my Ram 1500 hemi. Big increase in power in the lower to mid RPM range. Still a new product so waiting some more features to be released for my application.

The BDX tuner is awesome you can feel the HP... only disappointment is for my truck you can't change tire size so I have it combined with hypertech speed calibrator to gather they work great though...
