It ok but it didn't keep it from going from 8 to 4 cly

Better throttle response and better shift points.

I set the tuner for Towing, turned off the seatbelt chime and disabled the speed limiter. I am pleased with the much better throttle response and,after towing my travel trailer for a couple of hours, noticed better placed shifting while going up hills. Overall, I am happy with the tuner.

The bdx tuner made an immediate difference in my vehicle performance. I truck uses less gas, shifts gears smoother, and makes my truck sound amazing. It took about 30 minutes to install and about 10 minutes to change to each program setting. Installing the bdx tuner was the best investment I have made to enhance my trucks performance.

Not worth the Money

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.

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.

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...
