Range Active Fuel Management Disable Device Reviews


Works Excellent

Reviewed By Jonathan B (SARASOTA, FL) Reviewed for a 2015 GMC Yukon XL —3/20/2018 12:51 PM

This device works amazingly good. I never got an error code and my engine runs on 8 cylinders all the time. I have noticed better response on stand still take-off acceleration. I see a little improvement on the idle, but will probably improve more with changing the spark plugs and wires. It was incredibly easy to install, literally in seconds.

Bully Dog GT Platinum Tuner 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.

2004 gmc yukon xl denali 2500

Reviewed By shane f (Altoona, PA) Reviewed for a 2004 GMC Yukon XL —5/30/2015 5:13 AM

This programmer functioned as intended. It boosted horsepower about 10% which raised my average mpg by 21%. Three extra mpg may not seem like much, but when you're averaging 14 it really helps overall.
