Superchips Cortex Programmer Reviews

Works very well in all modes

Reviewed By William J M (Moncks Corner, SC) Reviewed for a 2006 GMC Yukon XL —11/23/2009 6:07 AM

I like the box so far. I've run all modes at times and like the benefits of each application. I am going to most likely run 87 octane setting. Have a custom tire size entered. That was such a NICE feature. Have modded the shift pressures and points in a custom config. Overall, I am happy with the product. GLiDE

Bully Dog Triple Dog GT Tuner (49-State Legal) Reviews

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.
