Superchips Cortex Programmer Reviews

Incredible Programmer

Reviewed By Christopher T (Charleston, WV) Reviewed for a 2007 GMC Yukon XL —8/10/2011 6:36 AM

I added new tires and rims to my Yukon XL. It was driving awful until I used the Cortex Programmer. It allowed me to set tire height and choose the 87 Octane tuner as well. I took the speed limiter off too. It shifts smooth and gets better gas mileage than it did before I put the larger tires on. It has much more power and really drives much better. Thank you Autoanything and Superchips. Without it, I would have went broke putting gas in the vehicle or would have had to sell the new rims and tires.

So easy!

Literally pulled it out of the package and plugged into the ECU. Took 5 seconds and its working. After experiencing what detrimental effects AFM has on a vehicle, this was a no brainer!

Great results EPA and performance!

Reviewed By Anthony L (Gig Harbor, WA) Reviewed for a 2000 GMC Yukon XL —10/7/2015 8:47 AM

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.
