The plastic carry-case that houses the E3 Downloader comes with a USB cable, the OBDII port connector cable, the instructions, and the programmer itself. Being that there are only four important pieces to keep track of, we're proud to report that this is one of the few instances that we haven't misplaced a part during an install.

These days, gas prices have a lot in common with that Zipper ride you see at the state fair each year. They're up, they're down, and they can easily make you feel sick. At press time, gas is relatively cheap, but it's doubtful this will last very long. This brings us to the age old question: performance or economy? Enter Bully Dog's new E3 Downloader - a programmer that you can set for better gas mileage and more power. Now, we can spend a day ripping around the desert with some enhanced kick and then highway it home with improved gas mileage, all the while laughing at stupid-looking hybrids. Isn't technology great?

We hooked our E3 Downloader to a thirsty Dodge Ram with a 5.7L Hemi, which is a perfect vehicle for this product. We like the Hemi's raw power (and certainly won't turn away more), but the thing goes through tanks of fuel faster than Editor Jones eats through bags of pork rinds. In addition to our Ram, the E3 Downloader can be used on more 50 different vehicles, spanning the spectrum of Dodge, Ford, GM, and Nissan trucks (even those using E85 fuel). Even cooler is the fact that it's cheaper than the other programmers produced by Bully Dog.

The thing couldn't have been easier to hook up, and once we did that, we realized it's a full-featured programmer. We calibrated the speedometer to the tire size, had the ability to read engine diagnostic codes (and erase them if appropriate), and noticed that we could change the vehicle's speed limiter settings. It's worth noting that the Downloader is designed to work in conjunction with 85- or 87-octane gas.

Depending on the application, Bully Dog tells us 10-12 hp can be gained with the E3 Downloader, and sure enough, we noticed an improvement of at least a couple miles per gallon (as usual, it's hard to get an accurate mileage number when you're flooring the gas pedal constantly). It's not often we make gains in both areas, so we'll chalk this up as a rare win-win experience.
