Worked just like you said and easy to install. Plug in and doesn't effect the engine light. Great!!!

Easy to use and easy to install. This item did exactly what it said. I purchaed my '09 Jeep Wrangler Rubicon with oversized tires (35 in. dia.) and from the dealer, the speedometer was way off and I was buring all sorts of fuel. After the reprogram, it was great. Gas was pretty good and the speedometer was right. Too bad the dealer (Chapman Jeep in Scottsdale, AZ) did not opt to correct, even though the item was purchased as they designed from the lot! All well, Hypertech took care of the problem at a reasonable price. One drawback, error codes must be called on and tech support is only open M-F (banker hours). If you purchased on the weekend, well, you just have to wait because the codes are not easily found...even online.

So far I have put about a thousand miles on my 2000Yukon XL with the bullydog and fuel averages went from fifteen to eighteen combined with a noticeable difference in performance of throttle response. It seems like in time the Bullydog will pay for itself and make the truck more usable with both power and MPG increases. Auto anything did a great job on price and getting it here quickly once again. I would definatly recommend this product to anyone and suggest auto anything as he place to get it.
