Gone are the days when you cannot do anything about the performance of your car if you are only able to afford one that is low-end. Today, you get more flexibility even if you only have a basic engine, and you can do that with the use of a power programmer. This upgrade is done in order to configure the performance of your car depending on what you desire, whether you need more torque for heavy towing, more horsepower for acceleration, or better fuel economy for fuel savings. Each of these three can be done to your vehicle using just a cord, a data port, and a programmer. One of the brands that shifts the power to you when it comes to your vehicle's performance is Bully Dog. But before buying its power programmer, let us first see what it is really capable of.
- 50-state legal
- Gives additional 23.5 horsepower and 30 pound-feet of torque
- With three different power levels
- Updatable and upgradeable via the internet
- Helps read and erase diagnostic trouble codes
- Carries a year of Bully Dog limited warranty
We tested this component on a 2007 Nissan Xterra and a 2007 Chevrolet Avalanche LTZ, and here is what we have to say:
- The unit looked good visually. The set-up wizard was easy to follow (though we needed to be really focused), and we did not even need to read the printed instructions.
- The Xterra and the Avalanche LTZ had a better throttle response and acceleration when set to the regular tune.
- We tried to put a slightly heavy load on the Avalanche LTZ in order to see if performance would be different. The operating parameter included a lower outside air temperature. The engine of the car performed okay, and we did not need to use higher octane fuel. No pinging or detonation occurred.
- The performance of the two vehicles generally improved by some. For the two vehicles, we saved an average of 1.5 gallons for the two-hour drive in the city. We got an amazing power increase of 18 horsepower and 27 pound-feet of torque, which definitely helped the two cars when assaulting inclines. Throttle response was really sharp.
- We had a horrific experience when downloading the settings for the Xterra. The unit started and went loading the settings, but the progress would stop at different levels, sometimes only at 14% or 92%. After that, the car would not start. We had to check the wiring connections to see if everything was fine. We made sure that the old programmer chip was removed so that there would be no interference. We checked everything. We tried a couple of times and finally got to 100%. We could have had the Xterra towed to the shop and the computer reconfigured if the problem was not fixed.
This product belongs to the mid-priced ones. Generally, we are not disappointed with the performance of this power programmer. The two vehicles received more points in the three settings. The very important thing to note is to purchase a programmer that is latest for the make, model, and year of your vehicle if you do not want additional expense for computer reconfiguring.
